A trip through Minneapolis rock concert history framed through psychedelic poster art In the years 1969-1970 the Minneapolis Labor Temple burned brightly as the center of the Twin Cities music scene. The Labor Temple was transformed into a rock club with a 1,200—person capacity and hosted famous acts such as the Grateful Dead, Spirit, Ten Years After, Muddy Waters, and the Byrds. This included several local bands like the Litter and Jokers Wild that would be opening acts. Cosmic Trip is the story of this famed club framed through the poster art of Juryj Ostroushko. The posters were inspired by the psychedelic art coming out of San Francisco at the time, each with hand—lettered typography used to simulate the effects of recreational drugs. This book moves chronologically through every concert hosted by the Labor Temple and each poster is accompanied by a descriptive review of the concert along with additional memorabilia. This duet of music history is a trip down memory lane.
