input: On March 1, 2010, an update on the Symphony X official website announced, that the band had recorded most of their next album and that Romeo and Allen were working on lyrics; Romeo was getting ready to start doing tracking for the album. The album's name and lyrical concept were revealed on January 29, 2011 in an interview by DJ JC Green of Metal Messiah Radio's "Heavy Metal Thunder" show with Russell Allen: the follow-up to Paradise Lost will be titled Iconoclast and will have its lyrics centered around "machines taking over everything and all this technology we put our society into pretty much being our demise." On March 25, 2011, it was announced on the Nuclear Blast website and Blabbermouth.net, that the new Symphony X album, Iconoclast, would be released in Europe on June 17 and in North America on June 21, as a Standard Edition as well as a 2-CD Digipack. Iconoclast debuted at number 76 on the Billboard 200 album chart in the United States, selling more than 7,300 copies in its first week. The record also debuted at number 7 on the Top Hard Rock Chart, number 19 on the Top Rock Chart and number 13 on the Top Independent Chart. The album showcases the highest chart position and the most first-week sales in the band's history. On February 25, 2011, Symphony X played the first show of their 2011 tour in Stuttgart, Germany, where they performed two songs from Iconoclast: "End of Innocence" and "Dehumanized". Some days later, in Antwerp, Belgium, they performed yet another new song, "Heretic". During their show in London, England, the band debuted another new song titled "Prometheus".

input: Hillary climbed ten other peaks in the Himalayas on further visits in 1956, 1960-1961, and 1963-1965. He also reached the South Pole as part of the Commonwealth Trans-Antarctic Expedition, for which he led the New Zealand section, on 4 January 1958. His party was the first to reach the Pole overland since Amundsen in 1911 and Scott in 1912, and the first ever to do so using motor vehicles. In 1960 Hillary organized an expedition to search for the fabled abominable snowman. Hillary was with the expedition for five months, although it lasted for ten. No evidence of Yetis was found, instead footprints and tracks were proven to be from other causes. During the expedition, Hillary travelled to remote temples which contained "Yeti scalps"; however after bringing back three relics, two were shown to be from bears and one from a goat antelope. Hillary said after the expedition: "The yeti is not a strange, superhuman creature as has been imagined. We have found rational explanations for most yeti phenomena". In 1962 he was a guest on the television game show What's My Line?; he stumped the panel, comprising Dorothy Kilgallen, Arlene Francis, Bennett Cerf, and Merv Griffin. In 1977, he led a jetboat expedition, titled "Ocean to Sky", from the mouth of the Ganges River to its source. From 1977 to 1979 he commentated aboard Antarctic sightseeing flights operated by Air New Zealand. In 1985, he accompanied Neil Armstrong in a small twin-engined ski plane over the Arctic Ocean and landed at the North Pole. Hillary thus became the first man to stand at both poles and on the summit of Everest. This accomplishment inspired generations of explorers to compete over what later was defined as Three Poles Challenge. In January 2007, Hillary travelled to Antarctica as part of a delegation commemorating the 50th anniversary of the founding of Scott Base.

input: D'Angelo signed a publishing deal with EMI Music in 1991 after catching the attention of record executives through a demo tape, which was originally by the group. After an impressive audition for EMI execs, a three-hour impromptu piano recital, D'Angelo was signed to a recording contract in 1993. A&R-man Gary Harris was primarily responsible for his signing, while manager Kedar Massenburg helped negotiate the contract as well. Massenburg became D'Angelo's manager after hearing of him through "the buzz on the streets". He had previously managed hip hop group Stetsasonic and formed the artist management-firm Kedar Entertainment in 1991, which he diversified into production, music publishing and publicity. In 1994, his first significant success came in the form of the hit single "U Will Know". D'Angelo co-wrote and co-produced the song for the all-male R&B supergroup Black Men United, which featured R&B singers such as Brian McKnight, Usher, R. Kelly, Boyz II Men, Raphael Saadiq and Gerald Levert. D'Angelo composed the music for "U Will Know", while his brother, Luther Archer, wrote the lyrics. Originally featured on the soundtrack to the film Jason's Lyric (1994), the single peaked at number 5 on the Hot R&B/Hip-Hop Singles & Tracks and at number 28 on the Billboard Hot 100. The music video for "U Will Know" featured D'Angelo as the group's choir director; he reprised the role for the live performance of the song at the Soul Train Music Awards. That same year, he wrote and produced the song "Overjoyed" for the Boys Choir of Harlem, which appeared on their studio album The Sound of Hope (1994). The success of "U Will Know" helped build the buzz surrounding D'Angelo, which was followed by a number of highly promoted showcases, and added to the buzz among music industry insiders. Brown Sugar was released in June 1995. Although sales were sluggish at first, the album was eventually a hit. The album debuted at number six on the US Billboard Top R&B Albums chart in the week of July 22, 1995. It ultimately peaked at number four in the week of February 24, 1996, and spent a total of 54 weeks on the chart. Brown Sugar also spent 65 weeks on the Billboard 200 and peaked at number 22 on the chart. It sold 300,000 copies within its two months of release. The album had been selling 35,000 to 40,000 copies a week through to November 1995, and by January 1996, it had sold 400,000 copies. With the help of its four singles, including the gold-selling Billboard Hot 100 hit "Lady" and R&B top-ten singles "Brown Sugar" and "Cruisin", the album reached sales of 500,000 copies in the United States by October 1995. On February 7, 1996, it was certified platinum by the Recording Industry Association of America, following shipments in excess of one million copies in the U.S. The album was certified gold in Canada on May 9, 2000. Its total sales have been estimated within the range of 1.5 million to over two million copies.
