Comedian/activist Margaret Cho has come a long way since her heady, pre-9/11 days of youthful dysfunction. (Read our Q&A with Cho here.)

In 2005, she wrote a collection of essays on all subjects political and pop called I Have Chosen to Stay and Fight; she starred in a feature-length documentary (Notorious C.H.O.) and starred in and wrote the script for the low-budget indie comedy, Bam Bam and Celeste. Then, of course, there was that stint on Dancing with the Stars.

In addition, she’s performed in a burlesque-style show, toured with ’80s pop stars like Cyndi Lauper, and is happily married to offbeat experimental artist Al Ridenour, with whom she collaborates on occasion.

This year, Cho did what many of us fantasize about — she became a rock star — and collaborated with her favorite musicians. In addition to learning to play guitar and polishing up her already gifted singing voice, Cho released a comedy-pop album, Cho Dependent, August 2010. It includes Tegan and Sara, Andrew Bird, Ani DiFranco, A.C. Newman (of the New Pornographers), Ben Lee and Fiona Apple. She performs a few tunes from the album during her live performance at Ruth Eckerd Hall tonight at 8 p.m., along with her usual rants, anecdotes and self-deprecating admissions. $39.50, $50. rutheckerdhall.com.
