IN: Keith Jarrett (born May 8, 1945) is an American jazz and classical music pianist. Jarrett started his career with Art Blakey, moving on to play with Charles Lloyd and Miles Davis. Since the early 1970s he has enjoyed a great deal of success as a group leader and a solo performer in jazz, jazz fusion, and classical music. His improvisations draw from the traditions of jazz and other genres, especially Western classical music, gospel, blues, and ethnic folk music.

In 1983, at the suggestion of ECM head Manfred Eicher, Jarrett asked bassist Gary Peacock and drummer Jack DeJohnette, with whom he had worked on Peacock's 1977 album Tales of Another, to record an album of jazz standards, simply titled Standards, Volume 1. Two more albums, Standards, Volume 2 and Changes, both recorded at the same session, followed soon after. The success of these albums and the group's ensuing tour, which came as traditional acoustic post-bop was enjoying an upswing in the early 1980s, led to this new standards trio becoming one of the premier working groups in jazz, and certainly one of the most enduring, continuing to record and tour for more than 25 years. The trio has recorded numerous live and studio albums consisting primarily of jazz repertory material. The Jarrett-Peacock-DeJohnette trio also produced recordings that consist largely of challenging original material, including 1987's Changeless. Several of the standards albums contain an original track or two, some attributed to Jarrett, but most are group improvisations. The live recordings Inside Out and Always Let Me Go (released in 2001 and 2002 respectively) marked a renewed interest by the trio in wholly improvised free jazz. By this point in their history, the musical communication among these three men had become nothing short of telepathic, and their group improvisations frequently take on a complexity that sounds almost composed. The standards trio undertakes frequent world tours of recital halls (the only venues in which Jarrett, a notorious stickler for acoustics, will play) and is one of the few truly successful jazz groups to play both straight-ahead (as opposed to smooth) and free jazz. A related recording, At the Deer Head Inn (1992), is a live album of standards recorded with Paul Motian replacing DeJohnette, at the venue in Delaware Water Gap, Pennsylvania, 40 miles from Jarrett's hometown, where he had his first job as a jazz pianist. It was the first time Jarrett and Motian had played together since the demise of the American quartet sixteen years earlier.

IN: Weezer is an American rock band formed in Los Angeles in 1992, consisting of Rivers Cuomo (lead vocals, lead guitar), Patrick Wilson (drums), Brian Bell (rhythm guitar, backing vocals, keyboards), and Scott Shriner (bass, backing vocals). After signing to Geffen Records in 1993, Weezer released their debut self-titled album, also known as the "Blue Album", in 1994. Backed by successful music videos for the singles "Buddy Holly", "Undone - The Sweater Song" and "Say It Ain't So", the Blue Album became a quadruple-platinum success.

Vocalist and lead guitarist Rivers Cuomo, drummer Patrick Wilson, bassist Matt Sharp and guitarist Jason Cropper formed Weezer in 1992. The band had its first practice on February 14 of that year; their first gig was closing for Keanu Reeves' band Dogstar shortly after. Weezer signed with Geffen Records on June 25, 1993, and the group recorded its debut album with producer Ric Ocasek at Electric Lady Studios in New York City. During the recording, Cropper left the band and was replaced by guitarist Brian Bell. Weezer (also referred to as the "Blue Album") was released in May 1994. Geffen originally did not wish to release a single, to see what sales could be generated by word-of-mouth alone. DJ Marco Collins of the Seattle radio station The End started playing "Undone - The Sweater Song", leading Geffen to release it as the first single. The music video was directed by Spike Jonze. Filmed in an unbroken take, it featured Weezer performing on a sound stage with little action, bar a pack of dogs swarming the set. The video became an instant hit on MTV. Jonze also directed the band's second video, "Buddy Holly", splicing footage from the 1970s television sitcom Happy Days with Weezer performing in a remade "Arnold's Drive-In." The video achieved heavy rotation on MTV and went on to win four MTV Video Music Awards, including Breakthrough Video and Best Alternative Music Video, and two Billboard Music Video Awards. The video was also featured on the companion CD for the Microsoft Windows 95 computer operating system. A third single, "Say It Ain't So", followed. Weezer is certified quadruple platinum in the United States, making it Weezer's best-selling album. It is certified triple platinum in Canada.
