Anderson Bruford Wakeman Howe (sometimes referred to by the abbreviation ABWH) was a project of four progressive rock musicians: vocalist Jon Anderson, drummer Bill Bruford, keyboardist Rick Wakeman, and guitarist Steve Howe (with Tony Levin on bass). They had played together in Yes in the early 1970s. With the exception of Anderson, the only remaining member of the line-up from that period, they had not been playing with Yes for many years. Anderson Bruford Wakeman Howe released one self-titled studio album in 1989 and a live recording from their immediately subsequent concert tour (advertised as "An Evening of Yes Music plus") in 1993. In the meantime, Arista Records had co-opted the material they had written for their second studio album for a 1991 "union" album of ABWH and members of the more recent Yes line-up around Chris Squire, who owned the rights to the name "Yes".
