Do It. TwentyWonder: A Carnival of the Mind.

If there's one "L.A." thing I'm still dying to do, it's to see the L.A. Derby Dolls in action. The rollerskating badasses play about twice a month, but tickets usually sell out pretty quickly, and can sometimes be pricey.

This month, though, they'll be playing for an extra special cause, as part of Twentywonder, a one-night-only benefit raising money for the Down Syndrome Association Of Los Angeles. Also on deck for the night: live performances by Black Rebel Motorcycle Club, Exene Cervenka (of X), Axis of Awesome, Funny or Die and more. Expect cirque performers and even the original Batmobile, as well as chances to a Fender guitar signed by Trent Reznor and a lunch for four hosted by Sam Simon (co-creator of The Simpsons).

Tickets go for $40 for general admission -- the usual top price for a Derby Dolls match. So not only can you see them play, you'll get to enjoy all these other amazing acts -- and all for charity. Get your tickets now.

TwentyWonder: A Carnival of the Mind takes place this Saturday, July 9 at 8pm at the Doll Factory, located at 1910 W. Temple St. in Filipinotown.
