The Fillmore East audience was in for a surprise when Miles Davis opened for the Steve Miller Band and Neil Young and Crazy Horse. The gig, was both the first of the Quintet's electric gigs and one of the band's last performances. The audience might not have been prepared for the fare; stunned might describe their response, but the night was historic for Davis aficionados.
As the exclusive designer for the Fillmore East, Byrd produced 11 posters for Bill Graham between 1968-71. With his architectural training, powerful linework and sense of dimension and balance, Byrd said his understanding of symmetry "... Led [me] right up to Art Nouveau. Add to that my LSD experiences, and it all connected up somehow." Byrd's credits include concert poster designs for Jimi Hendrix, the Who, the Grateful Dead, movie posters for Godspell and Jesus Christ Superstar, posters for The Pasadena Playhouse productions, cover art for TV Guide, and work for Warner Bros.
