Gut-wrenching pain and resentment, soul-deep and gunny-sacked for years, pervade True West by Sam Shepard and drive its characters to sub-human acts of desperation. Support these folks at Sundown Collaborative Theatre. Donate time and money- free pizza coupons, intermission refreshments and certificates to local thrift stores. (They’ll destroy a lot of furniture before the run’s end.) It’s okay. Their art’s in the right place.
