Question: Pavement and Wilco are both rock bands, which band consisted of Stephen Malkmus?

Wilco is an American alternative rock band based in Chicago, Illinois.  Wilco's lineup changed frequently during its first decade, with only singer Jeff Tweedy and bassist John Stirratt remaining from the original incarnation.  Since early 2004, the lineup has been unchanged, consisting of Tweedy, Stirratt, guitarist Nels Cline, multi-instrumentalist Pat Sansone, keyboard player Mikael Jorgensen, and drummer Glenn Kotche.  Wilco has released ten studio albums, a live double album, and four collaborations: three with Billy Bragg and one with The Minus 5.  The band was formed in 1994 by the remaining members of alternative country group Uncle Tupelo following singer Jay Farrar's departure. <SEP> Slay Tracks (1933–1969) (usually referred to as Slay Tracks) is American indie rock band Pavement's debut extended play (EP).  Pavement—at that time, a duo of just its two founding members Stephen Malkmus (guitar, vocals) and Scott Kannberg (guitar)—recorded "Slay Tracks" with producer and future member Gary Young (drums) during a four-hour session.  Pavement self-released the EP as a 7" vinyl record on the band's own record label Treble Kicker in 1989.  The music of "Slay Tracks" was influenced by indie and punk rock bands such as Swell Maps and The Fall, and many of the lyrics were inspired by life in the band's hometown of Stockton, California. <SEP> "Range Life" is a song by Pavement, the third single from their 1994 album "Crooked Rain, Crooked Rain".  The song attracted attention with controversial lyrics that seemed to mock alternative rock superstars the Smashing Pumpkins and the Stone Temple Pilots; Pumpkins frontman Billy Corgan expressed his displeasure in magazine interviews, while songwriter Stephen Malkmus maintained that his words had been misinterpreted and no insult was intended.  Regardless, Pavement, which was due to tour for Lollapalooza in 1994, got kicked out when the Smashing Pumpkins, the headlining act, threatened to cancel their Lollapalooza dates if Pavement played.  Pavement would eventually play Lollapalooza the next year.  An early 1993 demo of the song did not feature this verse; guitarist Spiral Stairs recalled in 2004 that when Malkmus first revealed these new lyrics to his bandmates at the New York City recording sessions for "CRCR", "we almost lost our lunch from laughing so much."  The single was not commercially released in the USA; it was issued by the band's UK label at the time, Big Cat.  Both B-sides are outtakes from the "Crooked Rain, Crooked Rain" sessions and are included on the 2004 of that album.  This song was one of many to be included in the group's greatest hits album "". <SEP>  The group mainly consisted of Stephen Malkmus (vocals and guitar), Scott Kannberg (guitar and vocals), Mark Ibold (bass), Steve West (drums) and Bob Nastanovich (percussion and vocals).  Initially conceived as a recording project, the band at first avoided press or live performances, while attracting considerable underground attention with their early releases. Pavement was an American indie rock band that formed in Stockton, California in 1989.  Gradually evolving into a more polished band, Pavement recorded five full-length albums and nine EPs over the course of their decade-long career, though they disbanded with some acrimony in 1999 as the members moved on to other projects.  In 2010, they undertook a well-received reunion tour.
