"EYEBALL" COLOR VINYL LP.
"Sing Out! features a stellar lineup of acoustic performances by Bay Area folk heroes, including Jerry Garcia and Bob Weir of the Grateful Dead, Country Joe McDonald, Kate Wolf, Rosalie Sorrels, and a percussion set by the Dead's drummers – billed as the Rhythm Devils. The event was described by Wavy Gravy as a "mini-Woodstock," and it is the last major show to be mixed and recorded by famed Grateful Dead soundman Owsley Stanley, aka "Bear." It is also the final live recording he made of any members of the Grateful Dead."
