If you're in LA, do yourself a favor and get to the Ahmanson to see Tracy Lett's August: Osage County. One of the most entertaining evenings I've ever had in the theatre. If you like dark, dark Edward Albee type humor, you'll really enjoy this one the cast, headed by Estelle Parsons, is absolutely perfect. It won the Pulitzer Prize last year. They have a limited number of $20 tix available for most performances as well.
