Great artistic experiences walk a fine line between avant-garde and laughably artsy. Ochre House has always been on point. Its theater productions are original, boundlessly creative, well-produced small wonders that leave audiences as pensive as they are delighted for a good few months after a show. Founder Matthew Posey is a courageous art conspirator who's long enriched the cultural scene through Ochre House's oddball characters, strikingly original plays and locally grown music and theatrical talent. The Exposition Avenue theater is a nook of uncompromising art in a vast landscape of commercialized entertainment. That alone is worth the ticket, but there's also a "donate what you can" night.
