'So Who's the Bass Player? The Ox Anthology' is a two-CD collection of the work of the late bassist for the Who, John Entwistle. It features rare recordings, spanning from the mid-1960s until his death in 2002. Included are songs written by Entwistle which were not included in some Who recordings, as well as songs which were rejected by the band originally. The album is a compilation of Entwistle's solo career and is chronologically arranged, starting with selections from his debut studio album, Smash Your Head Against the Wall, (1971) through his last, an album of music from the 1997–1998 cartoon series Van-Pires (Music from Van-Pires, 2000), and also includes live performances. Alice Cooper sings the lead vocals on two tracks, from Flash Fearless Vs. the Zorg Women, Pts. 5 & 6 (1975).
