I saw a lot of fantastic shows at this year's Revolutions International Theatre Festival, but the best of the lot, in my opinion, was Splinters, a brilliant theatrical metaphor for the conflict between religion and science created by the Tricklock Company's Kevin R. Elder and Summer Olsson. Elder is back with a new one-man show called Tangential that's directed by Olsson. I'm willing to bet the farm that this one will kick your butt. The show opens this Friday, March 18, with a special catered gala at 8 p.m. at the Tricklock Performance Space (112 Washington SE). $18. Tangential then runs Fridays and Saturdays at 8 p.m., and Sundays at 6 p.m. through April 10. $12 general, $9 students/seniors. 254-8393.
