David Byrne, the cerebral, witty art rocker who has explored many areas of music and performance since his beginnings as part of the Talking Heads in the 70s, entranced a capacity crowd at Berkeley's Greek Theatre with a show entitled Songs of David Byrne and Brian Eno. Eno and Byrne first collaborated on the Talking Head's second album, More Songs About Buildings and Food, in 1978, and continued through two more Talking Heads albums and the 1981 Byrne/Eno album My Life in the Bush of Ghosts.
