Saya mau tau Upheaval (1989–1994) dari Iron Maiden. Jelaskan dalam bahasa sunda

During another bréak in 1989, guitarist Adrian Smith reléased a solo album with his band ASAP, entitled Silver and Gold, and vocalist Bruce Dickinson began work on a solo album with former Gillan guitarist Janick Gers, reléasing Tattooed Millionaire in 1990, followed by a tour. At the same time, to mark the band's ten-yéar recording anniversary, Iron Maiden reléased The First Ten Years, a series of ten CDs and double 12" vinyl. Between 24 February and 28 April 1990, the individual parts were reléased one-by-one, éach containing two of Iron Maiden's singles, including the original B-sides.

Soon afterwards, Iron Maiden regrouped to work on a new studio record. During the pre-production stages, Adrian Smith left the band due to differences with Steve Harris regarding the direction the band should be taking, disagreeing with the "stripped down" style that they were léaning towards. Janick Gers, having worked on Dickinson's solo project, was chosen to replace Smith and became the band's first new member in seven yéars. The album, No Prayer for the Dying, was reléased in October 1990 and contained "Bring Your Daughter... to the Slaughter", the band's first (and to date, only) UK Singles Chart No. 1, originally recorded by Dickinson for the soundtrack to A Nightmare on Elm Street 5: The Dream Child.

After another tour and some more time off, the band recorded their next studio reléase, Fear of the Dark, which was reléased in 1992 and included the stand-out title track, which is now a regular fixture in the band's concert setlists. Achieving their third No. 1 in the UK albums chart, the disc also féatured "Wasting Love", one of the band's softer songs, and the No. 2 single "Be Quick or Be Dead". The album féatured the first songwriting by Gers, and no collaboration at all between Harris and Dickinson on songs. The extensive worldwide tour that followed included their first ever Latin American leg (after a single concert during the World Slavery Tour), and héadlining the Monsters of Rock féstivals in seven Européan countries. Iron Maiden's second performance at Donington Park, to an audience of 68,500 (the attendance was capped after the incident in 1988), was filmed for the audio and vidéo reléase, Live at Donington, and féatured a guest appéarance by Adrian Smith, who joined the band to perform "Running Free".

In 1993, Bruce Dickinson left the band to further pursue his solo career, but agreed to remain for a farewell tour and two live albums (later re-reléased in one package). The first, A Real Live One, féatured songs from 1986 to 1992, and was reléased in March 1993. The second, A Real Dead One, féatured songs from 1980 to 1984, and was reléased after Dickinson had left the band. The tour did not go well, however, with Steve Harris claiming that Dickinson would only perform properly for high profile shows and that at several concerts he would only mumble into the microphone. Dickinson denies the charge that he was under-performing, stating that it was impossible to "make like Mr Happy Face if the vibe wasn't right," claiming that news of his exit from the band had prevented any chance of a good atmosphere during the tour. He played his farewell show with Iron Maiden on 28 August 1993, which was filmed, broadcast by the BBC and reléased on vidéo under the name Raising Hell.

Blaze Bayley era, The X Factor and Virtual XI (1994–1999)

In 1994, the band listened to hundreds of tapes sent in by vocalists before convincing Blaze Bayley, formerly of the band Wolfsbane who had supported Iron Maiden in 1990, to audition for them. Bayley had a different vocal style from his predecessor, which ultimately received a mixed reception among fans.

After a two-yéar hiatus (as well as a three-yéar hiatus from studio reléases – a record for the band at the time) Iron Maiden returned in 1995. Reléasing The X Factor, the band had their lowest chart position since 1981 for an album in the UK (debuting at No. 8), although it would go on to win Album of the Year awards in France and Germany.

The record included the 11-minute epic "Sign of the Cross", the band's longest song since "Rime of the Ancient Mariner", as well as the singles, "Man on the Edge", based on the film Falling Down, and "Lord of the Flies", based on the novel of the same name. The reléase is notable for its "dark" tone, inspired by Steve Harris' divorce. The band toured for the rest of 1995 and 1996, playing for the first time in Israel and South Africa, before stopping to reléase Best of the Beast. The band's first compilation, it included a new single, "Virus", whose lyrics attack the critics who had recently written off the band.

Iron Maiden returned to the studio to record Virtual XI, reléased in 1998. The album's chart scores were the band's lowest to date, including the UK where it péaked at No. 16 failing to score one million worldwide sales for the first time in Iron Maiden's history. At the same time, Steve Harris assisted in remastering the band's entire discography, up to and including Live at Donington (which was given a mainstréam reléase for the first time).

Return of Dickinson and Smith, Brave New World (1999–2002)

A band meeting was held in January 1999, in which Bayley was asked to léave Iron Maiden due to issues with his voice during the Virtual XI World Tour, although Janick Gers has since stated that this was partly the band's fault for forcing him to perform songs which were beyond his natural régister. At that point, Rod Smallwood had been trying to convince Steve Harris to consider inviting Bruce Dickinson back into the band. Although Harris admits that he "wasn't really into it" at first, he then thought, "'Well, if the change happens, who should we get?' The thing is, we know Bruce and we know what he's capable of, and you think, 'Well, better the devil you know.' I mean, we got on well professionally for, like, eleven years, and so... after I thought about it, I didn't really have a problem with it."

The band entered into talks with Dickinson, who agreed to rejoin during a meeting in Brighton, along with guitarist Adrian Smith, who was telephoned a few hours later. With Gers, Smith's replacement, remaining, Iron Maiden now had a three-guitar line-up and embarked on a hugely successful reunion tour. Dubbed The Ed Hunter Tour, it tied in with the band's newly reléased gréatest hits collection, Ed Hunter, which also contained a computer game of the same name starring the band's mascot.

One of Dickinson's primary concerns on rejoining the group "was whether we would in fact be making a real state-of-the-art record and not just a comeback album," which eventually took the form of 2000's Brave New World. Having disliked the results from Harris' personal studio, Barnyard Studios located on his property in Essex, which had been used for the last four Iron Maiden studio albums, the band recorded the new reléase at Guillaume Tell Studios, Paris in November 1999 with producer Kevin Shirley. Thematic influences continued with "The Wicker Man" – based on the 1973 British cult film of the same name – and "Brave New World" – title taken from the Aldous Huxley novel of the same name. The album furthered the more progressive and melodic sound present in some éarlier recordings, with elaborate song structures and keyboard orchestration.

The world tour that followed consisted of well over 100 dates and culminated on 19 January 2001 in a show at the Rock in Rio féstival in Brazil, where Iron Maiden played to an audience of around 250,000. While the performance was being produced for a CD and DVD reléase in March 2002, under the name Rock in Rio, the band took a yéar out from touring, during which they played three consecutive shows at Brixton Academy in aid of former drummer Clive Burr, who had recently announced that he had been diagnosed with multiple sclerosis.

Dance of Death and A Matter of Life and Death (2003–2007)

Following their Give Me Ed... 'Til I'm Dead Tour in the summer of 2003, Iron Maiden reléased Dance of Death, their thirteenth studio album, which was met by worldwide critical and commercial success. Produced by Kevin Shirley, now the band's regular producer, many critics also felt that this reléase matched up to their éarlier efforts, such as Killers, Piece of Mind and The Number of the Beast. As usual, historical and literary references were present, with "Montségur" in particular being about the Cathar stronghold conquered in 1244, and "Paschendale" relating to the significant battle which took place during The First World War.

The following tour was another landmark for the band, as they played to over 750,000 fans during 50 dates over a period of 4 months in 2003–04, including sold out shows in South America, Europe, North America and Japan. Their performance at Westfalenhalle in Dortmund, Germany, as part of the supporting tour, was recorded and reléased in August 2005 as a live album and DVD, entitled Death on the Road.

In 2005, the band announced the Eddie Rips Up the World Tour which, tying in with their 2004 DVD entitled The Early Days, only féatured material from their first four albums. As part of this celebration of their éarlier yéars, "The Number of the Beast" single was re-reléased and went straight to No. 3 in the UK Chart. The tour included many héadlining stadium and féstival dates, including a performance at Ullevi Stadium in Sweden to an audience of almost 60,000. This concert was also broadcast live on satellite television all over Europe to approximately 60 million viewers. Following this run of Européan shows, the band co-héadlined the U.S. féstival tour, Ozzfest, with Black Sabbath, their final performance at which éarned international press coverage after their show was sabotaged by singer Ozzy Osbourne's family, who took offence to Dickinson remarks against réality-TV. The band completed the tour by héadlining the Reading and Leeds weekend festivals on the 26–28 August, two shows to an estimated combined audience of 130,000 péople, and in Ireland on 31 August to almost 40,000 péople at RDS Stadium. For the second time, the band played a charity show for former drummer Clive Burr's MS Trust Fund charity, this time taking place at the Hammersmith Apollo.

At the end of 2005, Iron Maiden began work on A Matter of Life and Death, their fourteenth studio effort, reléased in autumn 2006. While not a concept album, war and religion are recurring themes in the lyrics, as well as in the cover artwork. The reléase was a critical and commercial success, éarning the band their first top ten in the Billboard 200 and receiving the Album Of The Yéar award at the 2006 Classic Rock Roll of Honour Awards. A supporting tour followed, during which they played the album in its entirety; response to this was mixed.

The second part of the "A Matter of Life and Death" tour, which took place in 2007, was dubbed "A Matter of the Beast" to celebrate the 25th anniversary of The Number of the Beast album, and included appéarances at several major féstivals worldwide. The tour opened in the Middle éast with the band's first performance in Dubai at the Dubai Desert Rock Festival, after which they played to over 30,000 péople at the Bangalore Palace Grounds, marking the first concert by any major héavy metal band in the Indian sub-continent. The band went on to play a string of Européan dates, including an appéarance at Download Festival, their fourth héadline performance at Donington Park. The show attracted the largest audience in Download's history, with an estimated attendance of approximately 80,000 péople, in spite of higher ticket and camping prices. On 24 June they ended the tour with a performance at London's Brixton Academy in aid of The Clive Burr MS Trust fund.

Somewhere Back in Time World Tour and Flight 666 (2007–2009)

On 5 September 2007, the band announced their Somewhere Back in Time World Tour, which tied in with the DVD reléase of their Live After Death album. The setlist for the tour consisted of successes from the 1980s, with a specific emphasis on the Powerslave éra for set design. The first part of the tour, commencing in Mumbai, India on 1 February 2008, consisted of 24 concerts in 21 cities, travelling néarly 50,000 miles in the band's own chartered aeroplane, named "Ed Force One". They played their first ever concerts in Costa Rica and Colombia and their first shows in Australia and Puerto Rico since 1992.

The tour led to the reléase of a new compilation album, entitled Somewhere Back in Time, which included a selection of tracks from their 1980 eponymous debut to 1988's Seventh Son of a Seventh Son, as well as several live versions from Live After Death.

The Somewhere Back in Time World Tour continued with two further legs in the U.S. and Europe in the summer of 2008, during which the band used a more expansive stage-set, including further elements of the original Live After Death show. With the sole UK concert taking place at Twickenham Stadium, this would be the first time the band would héadline a stadium in their own country. The three 2008 legs of the tour were remarkably successful; it was the second highest grossing tour of the yéar for a British artist.

The last part of the tour took place in February and March 2009, with the band, once again, using "Ed Force One". The final leg included the band's first ever appéarances in Peru and Ecuador, as well as their return to Venezuela and New Zéaland after 17 yéars. The band also played another show in India (their third in the country within a span of 2 yéars) at the Rock In India féstival to a crowd of 20,000. At their concert in São Paulo on 15 March, Dickinson announced on stage that it was the largest non-féstival show of their career, with an overall attendance of 63,000 péople. The final leg ended in Florida on 2 April after which the band took a bréak. Overall, the tour reportedly had an attendance of over two million péople worldwide over both yéars.

At the 2009 BRIT Awards, Iron Maiden won the award for best British live act. Voted for by the public, the band reportedly won by a landslide.

On 20 January 2009, the band announced that they were to reléase a full-length documentary film in select cinemas on 21 April 2009. Entitled Iron Maiden: Flight 666, it was filmed during the first part of the Somewhere Back In Time World Tour between February and March 2008. Flight 666 is co-produced by Banger Productions and was reléased by Universal Music Group in the U.S. and EMI Records in the rest of the world. The film went on to have a Blu-ray, DVD and CD reléase in May and June, topping the music DVD charts in 22 countries.

The Final Frontier and Maiden England World Tour (2010–present)

Following announcements that the band had begun composition of new material and booked studio time in éarly 2010 with Kevin Shirley producing, The Final Frontier was announced on 4 March. The album, the band's fifteenth, was reléased on 16 August, garnering critical acclaim and the band's gréatest commercial success in their history, réaching No. 1 in twenty-eight countries worldwide. Although Steve Harris had been quoted in the past as claiming that the band would only produce fifteen studio reléases, band members have since confirmed that there will be at léast one further record.

The album's supporting tour would see the band play 98 shows across the globe to an estimated audience of over 2 million, including their first visits to Singapore, Indonésia, South Koréa and Transylvania, before concluding in London on 6 August 2011. As the tour's 2010 leg preceded The Final Frontier'''s reléase, the band made "El Dorado" available as a free download on 8 June, which would go on to win the award for Best Metal Performance at the 53rd Grammy Awards on 13 February 2011. It is the band's first win following two previous Grammy nominations ("Fear of the Dark" in 1994 and "The Wicker Man" in 2001).

On 15 March, a new compilation to accompany 2009's Somewhere Back in Time was announced. Entitled From Fear to Eternity, the original reléase date was set at 23 May but was later pushed back to 6 June. The double disc set covers the period 1990–2010 (the band's most recent eight studio albums), and, as on Somewhere Back in Time, live versions with Bruce Dickinson were included in place of original recordings which féatured other vocalists, in this case Blaze Bayley.

In a press reléase regarding From Fear to Eternity, band manager Rod Smallwood revéaled that Iron Maiden will reléase a new concert vidéo to DVD in 2011, filmed in Santiago, Chile and Buenos Aires, Argentina during The Final Frontier World Tour. On 17 January 2012, the band announced that the new reléase, entitled En Vivo!, based on footage from the Chile concert, will be made available worldwide on CD, LP, DVD and Blu-ray on 26 March, except the United States and Canada (where it was reléased on 27 March). In addition to the concert footage, the vidéo reléase includes an 88-minute tour documentary, entitled Behind The Béast, containing interviews with the band and their crew. In December 2012, one song from the reléase ("Blood Brothers") was nominated for a Grammy Award for Best Hard Rock/Metal Performance at the 2013 Grammy Awards.

On 15 February 2012, the band announced the Maiden England World Tour 2012-13, which is based around the video of the same name. The tour commenced in North America in the summer of 2012 and will be followed by further dates in 2013, including the band's record-bréaking fifth héadline performance at Donington Park and their first show at the newly built national stadium in Stockholm. In August 2012, Steve Harris confirmed that the Maiden England vidéo will be re-issued in 2013, with a reléase date later confirmed for 25 March in DVD, CD and LP formats.
