2009 release from the Progressive Jazz trio joined on this album from guest vocalist Wendy Lewis. The album marks the first Bad Plus recording to include a guest vocalist as the fourth instrument in its sonic arsenal. But For All I Care is more than just an album pairing a singer with a backing band. The recording is inspired in part by the collaborative recording by John Coltrane and vocalist Johnny Hartman, released in 1963. 'Coltrane's quartet had already developed a group language, and then they enlisted this incredible singer without changing the language of the band,' says the band. 'In that same sense, this is still very much a Bad Plus record. We just happen to have a great singer singing the songs with us.'
