In 1969 and 1970 the Minneapolis Labor Temple burned bright as the center of the Twin Cities music scene. The ballroom of the Labor Temple in Southeast Minneapolis, site of union meetings, was transformed into a rock club with a 1,200-person capacity and hosted famous bands such as the Grateful Dead, Spirit, Ten Years After, Muddy Waters, and the Byrds. Local bands like the Litter and Jokers Wild were opening acts.

Cosmic Trip tells the story of this famed club framed through the poster art of Juryj Ostroushko. His posters were inspired by the psychedelic art coming out of San Francisco at the time, and each features hand-lettered typography that simulates the effects of recreational drugs. This book moves chronologically through every concert at the Labor Temple, with a descriptive review of the concert along with its poster and additional memorabilia. This duet of music and art is a trip down memory lane during a trippy time of Minneapolis rock.
