Background: The Goo Goo Dolls (originally Sex Maggot) are an American rock band formed in 1986 in Buffalo, New York, by vocalist and guitarist John Rzeznik, vocalist and bassist Robby Takac, and drummer George Tutuska. Mike Malinin was the band's drummer from January 1995 until December 27, 2013 (but not made an official member until 1998). Although renowned for their commercially successful 1998 single "Iris", they have had several other notable and popular singles including "Name" and "Naked" from 1995's A Boy Named Goo, "Slide", "Black Balloon", "Dizzy", and "Broadway" from 1998's Dizzy Up the Girl, "Here Is Gone" from 2002's Gutterflower, "Better Days", "Give a Little Bit", and "Stay with You" from 2006's
Context: The band's original lineup included John Rzeznik (vocals, guitar), Robby Takac (vocals, bass), and George Tutuska (drums, percussion). Takac and Tutuska had been long-time friends in school and met Rzeznik while he was playing in the band The Beaumonts with Takac's cousin, Paul Takac and close friend Michael Harvey who was the inspiration for the band. The trio picked their name from a True Detective ad for a toy called a Goo Goo Doll. "We were young and we were a garage band not trying to get a deal. We had a gig that night and needed a name. It's the best we came up with, and for some reason it stuck. If I had five more minutes, I definitely would have picked a better name", John stated. With Takac as their lead singer, the band released their first album, Goo Goo Dolls in 1987 on Mercenary Records, but was picked up in 1988 by Celluloid Records, a larger record company. They played around Buffalo's underground music circuit opening for punk bands such as SNFU, Dag Nasty, ALL, The Dead Milkmen, Gang Green, Doughboys, and DRI and playing with fellow Buffalo bands. The band released its second album Jed in 1989.  The band released its third album, Hold Me Up, in 1990 and featured Rzeznik as the lead vocalist on five tracks, including the single, "There You Are"--as well as their then concert favorite, "Two Days in February". After being embraced by local college radio and punk scenes (including playing such venues as CBGB), the Goo Goo Dolls' third release incorporated elements of heavy metal, pop rock, and punk rock. In 1991, the song "I'm Awake Now" was recorded for the soundtrack of Freddy's Dead: The Final Nightmare.  Superstar Car Wash, released in 1993, received significant media attention. The critical success and encouraging sales of their last album resulted in a larger budget from Metal Blade Records. The album was partially recorded at Metalworks Studios in Mississauga, Ontario. "We Are the Normal" (the single for which Rzeznik asked frontman Paul Westerberg of The Replacements to write the lyrics) received a major push toward play on college and independent radio, while its video was displayed on MTV's 120 Minutes program. "Fallin' Down" made it onto the 1993 soundtrack of Pauly Shore's hit film Son in Law.

Problem: Background: Mazzy Star is an American alternative rock band formed in Santa Monica, California, in 1989 from remnants of the group Opal. Founding member David Roback's friend Hope Sandoval became the group's vocalist when Kendra Smith left Opal. Mazzy Star is best known for the song "Fade into You" which brought the band some success in the mid-1990s and was the group's biggest mainstream hit, earning extensive exposure on MTV, VH1, and radio airplay. Roback and Sandoval are the creative center of the band, with Sandoval as lyricist and Roback as composer of the majority of the band's material.
Context: In Mazzy Star, Roback plays guitar, keyboard, and piano. He wrote almost all music for Mazzy Star, and he has also produced all their recordings.  Roback grew up in Pacific Palisades, California, graduating from Palisades High School in 1975. He started a band called Rain Parade with his brother Steven. They first hit the scene in 1982 as part of a loose aggregate of psychedelic 1960s-influenced guitar bands in Los Angeles, and they were in the forefront of that movement which lasted a couple of years.  After Rain Parade's first album and tours, Roback left the band. He then became involved with ex-Dream Syndicate bassist Kendra Smith and formed a new band called Clay Allison in 1983. The recordings from the summer this year remained unreleased until the 1989 release of Opal Early Recordings.  After Clay Allison's 1984 tour, the band decided to go with a name change, and went from Clay Allison to Opal, whose sound was defined by Roback's spare, distorted guitar work and Smith's vocals. They released the Northern Line EP in 1985. SST Records signed Opal and released their album Happy Nightmare Baby on December 14, 1987. During the Opal tour in December 1987, Smith left the band. She was replaced by Sandoval, and they toured Europe through early 1988. Roback and Sandoval had an intimate relationship at this time and after Opal was disbanded, they took the remaining members of Opal and changed their name to Mazzy Star.  Roback currently resides in London, although he spent most of the past decade living in Norway.
