Question:
Beastie Boys were an American rap rock group from New York City, formed in 1981. For the majority of their career, the group consisted of Michael "Mike D" Diamond (vocals, drums), Adam "MCA" Yauch (vocals, bass) and Adam "Ad-Rock" Horovitz (vocals, guitar). Originally formed as a four-piece hardcore punk band, the Young Aborigines, in 1978 by Diamond (vocals), John Berry (guitar), Yauch (bass) and Kate Schellenbach (drums), the band appeared on the compilation cassette New York Thrash, contributing two songs from their first EP, Polly Wog Stew, in 1982. Berry left shortly thereafter, and was replaced by Horovitz.
Prior to forming the Beastie Boys, Michael Diamond was part of a number of bands such as the Walden Jazz Band, BAN, and The Young Aborigines. The Beastie Boys formed in July 1981 when the Young Aborigines bassist Jeremy Shatan left New York City for the summer and the remaining members Michael Diamond, John Berry and Kate Schellenbach formed a new hardcore punk band with Adam Yauch called Beastie Boys. The band supported Bad Brains, the Dead Kennedys, the Misfits and Reagan Youth at venues such as CBGB, A7, Trudy Hellers Place and Max's Kansas City, playing at the latter venue on its closing night. In November 1982, the Beastie Boys recorded the 7" EP Polly Wog Stew at 171A studios, an early recorded example of New York hardcore. On November 13, 1982, the Beastie Boys played Philip Pucci's birthday for the purposes of his short concert film of the Beastie Boys, Beastie. Pucci held the concert in Bard College's Preston Drama Dance Department Theatre. This performance marked the Beastie Boys' first on screen appearance in a published motion picture. Pucci's concept for Beastie was to distribute a mixture of both a half dozen 16 mm Bell & Howell Filmo cameras, and 16 mm Bolex cameras to audience members and ask that they capture the Beastie Boys performance from the audience's own point of view while a master sync sound camera filmed from the balcony of the abandoned theater where the performance was held. The opening band for that performance was The Young and the Useless, which featured Adam Horovitz as the lead singer. A one-minute clip of Beastie was subsequently excerpted and licensed by the Beastie Boys for use in the "Egg Raid on Mojo" segment of the "Skills to Pay the Bills" long-form home video released by Capitol Records. "Skills to Pay the Bills" later went on to be certified Gold by the Recording Industry Association of America (RIAA). Berry left the group in 1982 (later forming Thwig, Big Fat Love and Bourbon Deluxe) and was replaced by Adam Horovitz, guitarist of The Young and the Useless, who had become close friends with the Beastie Boys at this point; Schellenbach left the band in 1984 and was not replaced, with Diamond filling the role of drummer. The band also recorded and then performed its first hip hop track, "Cooky Puss", based on a prank call by the group to Carvel Ice Cream franchise in 1983. It was a part of the new lineup's first EP, also called Cooky Puss, which was the first piece of work that showed their incorporation of the underground rap phenomenon and the use of samples. It quickly became a hit in New York underground dance clubs and night clubs upon its release. In 1983, the new lineup released the Cooky Puss EP, which offered the first evidence of them picking up on the underground rap phenomenon and the use of samples. "Beastie Revolution" was later sampled for a British Airways commercial. The Beastie Boys sued them over the use of the song, earning them $40,000 in royalties.

Question:
Gnarls Barkley is an American soul duo, composed of singer-songwriter CeeLo Green and producer Danger Mouse. They have released two studio albums, St. Elsewhere (2006) and The Odd Couple (2008). St. Elsewhere was recorded on the Warner Music UK label, and contained their hit single "Crazy" which topped at number two on the US Hot 100, and topped the charts in the UK. It was also nominated at the 2007 Grammy Awards for Record of the Year, and was platinum certified for shipping over 1,000,000 records.
In early March 2008, the duo's second album, The Odd Couple, was leaked over the internet prompting the duo to push the release date up from April 8. In an interview with Entertainment Magazine, Danger Mouse said that he "knew it [the leak] was coming...every day, I expected to get a call saying it leaked, and eventually I got a call saying it leaked." On March 18, 2008, the album became available via download on the iTunes Store and Amazon MP3. Hard copies of the album were released on March 25. Prior to its official release, Green spoke to the album's anti-formulaic qualities, noting bluntly that "there's no formula to it," and that to expect the same wild success of St. Elsewhere is to neglect the ever-present "risk factor in any artistic endeavor." He called it something of an "act of faith" - a true, earnest attempt to create and disseminate a piece of art to those who would seek out its conception. They appeared as the musical guest on the April 12, 2008 episode of NBC's Saturday Night Live. They were supposed to be in a Digital Short parodying amateur music videos according to the scrolled text but only appeared in the singing performances of the live broadcast. On November 11, 2008, they released an EP, Who's Gonna Save My Soul, featuring four versions of the song which originally appeared on The Odd Couple, along with a live version of "Neighbors" and a previously unreleased song, "Mystery Man." A music video for "Mystery Man" was directed by Walter Robot and premiered on Yahoo! Music.
