Background: Kanjani Eight (Guan ziyani[?](eito), Kanjani Eito, stylized as Kanjani[?]) is a seven-member Japanese boy band from Japan's Kansai region. They are managed by the multimedia talent agency, Johnny & Associates, and signed to Imperial Records. The group was formed in 2002 and made their CD debut in 2004 as "Johnny's modern enka group", though after the year 2006, their sound and style has become a mix of pop and rock. Like the rest of the acts managed under Johnny & Associates, Kanjani Eight also perform in various other areas of the Japanese entertainment industry such as variety show hosting, television, movie, and stage acting, and radio talk show hosting.
Context: Although Nishikido and Uchi were already members of NEWS, they went on to also debut as members of Kanjani Eight when the group released their debut single titled "Naniwa Iroha Bushi" in the Kansai area on August 25, 2004. The single became a local hit, capturing the traditional feel of their hometown region through the pop-enka tune. Shibutani had said, in regards to the feel of the song, " The song has a Kawachi Workman's bass, so it's entirely something new. It'd make me happy to see others dancing when they hear it." Despite the release of the CD, their debut was lackluster, leaving many to question if the debut actually was real. The members themselves had found out of the debut through a newspaper article; Shibutani had said that he was "very surprised" when he found out. Even though there was questions about the group's debut, "Naniwa Iroha Bushi" had risen to the number-one spot on the Oricon's Enka charts and reaching number-eight on the Oricon's generic music charts. When the single made its nationwide debut on September 22, it had hit number-one on both the Oricon Enka and General Music charts. Much of 2004 activities were Kansai region focused in comparison their fellow acts who had the luxuries of nationwide exposure. Kanjani Eight had become hometown idols with majority of their popularity within the region but outside the area they were almost unknown. The release of their second single, "Osaka Rainy Blues", further exemplified the fact with the CD single debuting number-nine on the Oricon. To this date, "Osaka Rainy Blues" is the group's lowest single in sales. 2005 had marked the launch of Kanjani Eight's popularity even though it had opened up with the lackluster sales of their second single, "Osaka Rainy Blues". The group had been starring in three regular programs, now being aired nationwide, and were starting to get recognition as a debut Johnny's act. But with growing success came a scandal and in 2005 Hiroki Uchi was arrested for disorderly conduct and underage drinking, being 18 at the time. The scandal had a significant impact on Kanjani Eight as well as NEWS, the other group he was active in. Johnny's & Associates removed Uchi from both units and put him under an indefinite hiatus from all activities. Also, the drama special about the World War II Kamikaze pilots starring the group, Yakusoku, was canceled. Kanjani Eight continued on that year to do their first Osaka-jo Hall performance with one member less in the summer of 2005.
Question: When was the first concert?
Answer: 2005 had marked the launch of Kanjani Eight's popularity

Background: ZZ Top is an American rock band formed in 1969 in Houston, Texas. The band has, since 1970, consisted of bassist and lead vocalist Dusty Hill, guitarist and lead vocalist Billy Gibbons (the band's leader, main lyricist and musical arranger), and drummer Frank Beard. "As genuine roots musicians, they have few peers", according to former musician, critic and collector Michael "Cub" Koda. "Gibbons is one of America's finest blues guitarists working in the arena rock idiom [...] while Hill and Beard provide the ultimate rhythm section support."
Context: ZZ Top's next album was even more successful. Eliminator, released in March 1983, featured two top 40 singles ("Gimme All Your Lovin'" and "Legs"), and two additional Top Rock hits ("Got Me Under Pressure" and "Sharp Dressed Man"), with "Legs" peaking at no. 13 on the Club Play Singles chart. Eliminator was a critical and commercial success, selling more than 10 million copies, and several music videos were in regular rotation on MTV. The band also won their first MTV Video Music Awards in the categories of Best Group Video for "Legs", and Best Direction for "Sharp Dressed Man". The music videos were included in their Greatest Hits video, which was later released on DVD and quickly went multiple-platinum. However, the Eliminator album was not without controversy. According to former stage manager David Blayney in his book "Sharp Dressed Men", sound engineer Linden Hudson co-wrote much of the material on the album while serving as a live-in high-tech music teacher to Beard and Gibbons. Despite continued denials by the band, it settled a five-year legal battle with Hudson, paying him $600,000 after he proved he held the copyright to the song "Thug". Despite not selling as many copies as Eliminator, 1985's Afterburner became the band's highest-charting album, racking up sales of five million units. All of the singles from Afterburner were Top 40 hits, with two ("Sleeping Bag" and "Stages") hitting no. 1 on the Mainstream Rock chart. The music video for "Velcro Fly" was choreographed by pop singer Paula Abdul. ZZ Top's grueling Afterburner World Tour lasted well into 1987, which also saw the release of The ZZ Top Sixpack, a three-disc collection of ZZ Top's albums from 1970 to 1981, with the exception of Deguello. The albums ZZ Top's First Album, Rio Grande Mud, Tres Hombres, Fandango, and Tejas were remixed to have a more contemporary sound. Recycler, released in 1990, was ZZ Top's last studio album under contract with Warner Records. Recycler was also the last of a distinct sonic trilogy in the ZZ Top catalogue, marking a return towards a simpler guitar-driven blues sound with less synthesizer and pop bounce than the previous two albums. This move did not entirely suit the fan base that Eliminator and Afterburner had built up, and while Recycler did achieve platinum status, it never matched the sales of those albums.
Question: What other albums were released during this time period?

The ZZ Top Sixpack, a three-disc collection of ZZ Top's albums
