Background: 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.
Context: 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.  Weezer completed the Pinkerton tour in mid-1997 and went on hiatus. Wilson returned to his home in Portland, Oregon to work on his side project, the Special Goodness, and Bell worked on his band Space Twins. Sharp left Weezer to complete the follow-up album for his group the Rentals. He said of his departure from Weezer: "I don't really know how to speak on this because I don't know what should be kept private and what should be shared. I certainly have my view of it, as I'm sure everybody else has their sort of foggy things. When you have a group that doesn't communicate, you're going to have a whole lot of different stories."  Cuomo returned to Harvard but took a break to focus on songwriting. He formed a new band composed of a changing lineup of Boston musicians, and performed new material, including possible songs for the next Weezer album. Wilson eventually flew to Boston to join as Homie's drummer. The songs were abandoned, but live recordings of the Boston shows are traded on the internet.  In February 1998, Cuomo, Bell and Wilson reunited in Los Angeles to start work on the next Weezer album. Rumors suggest Sharp did not rejoin the band and left the group in April 1998, which Sharp denies. The group hired Mikey Welsh, who had played with Cuomo in Boston, as their new bassist. Weezer continued rehearsing and cut demos until the fall of 1998. Frustration and creative disagreements led to a decline in rehearsals, and in late 1998, Wilson left for his home in Portland pending renewed productivity from Cuomo. In November 1998, the band played two club shows with a substitute drummer in California under the name Goat Punishment, consisting entirely of covers of Nirvana and Oasis songs. In the months following, Cuomo entered a period of depression, painting the walls of his home black and putting fiberglass insulation over his windows to prevent light entering.  Weezer did not reunite until April 2000, when the Fuji Rock Festival in Japan made Weezer a lucrative offer to play in August 2000. The festival served as a catalyst for Weezer's productivity, and from April to May 2000, the band rehearsed and demoed new songs in Los Angeles. They returned to live shows in June 2000, playing small unpromoted concerts under the name Goat Punishment. In June 2000, the band joined the American Warped Tour for nine dates.  In the summer of 2000, Weezer went on tour (including dates on the popular Vans Warped Tour). The band's setlist consisted of 14 new songs; when 13 of these songs did not appear on Weezer's next album, fans of the songs started a petition demanding the release of studio versions. Eventually, the band went back into the studio to produce a third album. The band chose the title Weezer (2001) to repeat the self-titled name of the band's first release. This album became known as the Green Album due to its green album artwork. Shortly after the release, Weezer went on another American tour. The band attracted a new generation of fans thanks to heavy MTV rotation for the videos of the band's hit singles "Hash Pipe" and "Island in the Sun".  As reported on August 16, 2001, by MTV, Welsh was checked into a psychiatric hospital. His whereabouts were previously unknown, as he went missing before the filming of the second video for "Island in the Sun". Weezer was prompted to find a temporary replacement for Welsh. Through a mutual friend, Cuomo received Scott Shriner's number and asked if he was interested in filling in for Welsh. Shriner accepted the invitation.
