Question: Which band had more members in its original line-up, 311 or Mercury Rev?
Context: 311 (pronounced "three-eleven") is an American rock band from Omaha, Nebraska.  The band was formed in 1988 by vocalist and guitarist Nick Hexum, lead guitarist Jim Watson (a member briefly, before being replaced by Tim Mahoney in 1991), bassist Aaron "P-Nut" Wills.  and drummer Chad Sexton.  In 1992, Doug "SA" Martinez joined to sing and provide turntables for 311's later albums, rounding out the current line-up.  The band's name originates from the police code for indecent exposure in Omaha, Nebraska, after the original guitarist for the band was arrested for streaking. In a Priest Driven Ambulance (With Silver Sunshine Stares) is the fourth album by The Flaming Lips, released in 1990 (see 1990 in music).  It is a concept album primarily focused on frontman Wayne Coyne's fascination with religion.  It is generally considered among critics to be one of the Flaming Lips' greatest albums.  It is the first Flaming Lips album to feature Jonathan Donahue (also of Mercury Rev) and drummer, Nathan Roberts.  This line-up would subsequently be signed by Warner Bros.  Records and go on to record the follow-up album, "Hit to Death in the Future Head" Mercury Rev is an American indie rock band formed in 1989 in Buffalo, New York.  Original personnel were David Baker (vocals), Jonathan Donahue (vocals, guitars), Sean Mackowiak, a.k.a. "Grasshopper" (guitars, clarinet), Suzanne Thorpe (flute), Dave Fridmann (bass) and Jimy Chambers (drums). Justin Russo (born June 30, 1976) is a singer-songwriter-guitarist-pianist from Upstate New York.  Russo began his career as a musician at the age of 18 by joining his older brother's band Hopewell, which focused mainly on psychedelic rock balladry and lengthy "shoegazing" soundscapes.  After releasing their first record "Contact" on Burnt Hair Records, both brothers took a break from their own project and joined indie/experimental band Mercury Rev. Hopewell is an American rock band.  The band was founded by Jason Sebastian Russo, of Hopewell Junction, New York.  At 19, Russo joined Mercury Rev, and then struck out on his own with a band named after his hometown. "Holes" is the fourth single from Mercury Rev's fourth studio album, "Deserter's Songs".  The single was released in Australia only as a limited edition tour EP on July 7, 1999, although promotional CD singles were distributed to UK radio stations in 2006 (to coincide with the release of the Mercury Rev collection "").  The tour single included a live cover of "Caroline Says Pt.  II" (Lou Reed) and featured Robert Creeley reading his poem "I Dreamt" over a Mercury Rev soundtrack. Boces is the second album by Mercury Rev, released in 1993.  The band has explained the title as being inspired by the name of the Boards of Cooperative Educational Services in New York State, a vocational school system in the band's home state. The Light in You is the ninth studio album by American rock band Mercury Rev, released on October 2, 2015 by Bella Union.  "The Light in You" is the band's first entirely self-produced and recorded album, as well as the first not to be produced by longtime collaborator Dave Fridmann. David Baker is the former lead singer and founding member of the band Mercury Rev.  He is prevalent on the albums "Yerself Is Steam" and "Boces" and all of the singles and Peel Sessions the band did concurrently.  Mercury Rev's sound changed considerably after the departure of Baker, whose deep voice was replaced by the much higher-pitched singing of Jonathan Donahue. Comet is an American indie rock band that was formed in 1993 in the Dallas, Texas suburb of Mesquite.  Described as an enigmatic noise pop outfit brought together by a common love of the Beatles, the original lineup of singer/guitarist Jim Stone, his bassist-brother Neil Stone, guitarist Daniel Huffman, and percussionist Josh Garza entered the studio later that year to cut their debut single "Portrait," produced by Mercury Rev alum David Baker.  A deal with the Arista subsidiary Dedicated label followed, they became label mates with Spiritualized, Beth Orton and the Cranes and with Baker again at the helm, Comet recorded their LP bow "Chandelier Musings", issued in late 1996.  The band toured throughout much of 1995 and 1996 and into early 1997 when fallout from a tour-van accident led to the eventual break up of the original line-up.
