This exhibition will explore ideas of perception and representation through a site-specific installation constructed by the artist. Birmingham-based artist Jurgen Tarrasch is interested in abstraction as a medium. He uses painting to explore means of expression and art’s capacity to convey complexity. An opening reception is planned for 5 to 8 p.m. Thursday, Sept. 2 in The Gallery at UAB, 900 13th St. South. Admission is free. Call 205-934-0815.
