Yes, they're bluer than blue. And they're just about the most engaging avant-garde theatrical experience out there. Blue Man Group offers an escape from the ordinary through an explosive convergence of comedy and multi-media technology, including a massive LED curtain and high-resolution screen, as well as the haunting, driving rhythms of a live band. The touring production includes new material plus fan favorites. Closes this Sunday, April 3. Warner Theatre, 513 13th St. NW. Call 202-783-4000 or visit warnertheatre.com.
