Janeane Garofalo, a firebrand actress, former talk show host and all-around liberal activist wears a lot of hats – her credits include Saturday Night Live, West Wing, 24, Reality Bites and Ratatouille. But she’s first and foremost a standup comedian, making informed, unflinching observations about current events – not unlike Kathy Griffin, though her lens is more trained on Washington and national politics, not so much Hollywood and showbiz. Sounds perfect for a Washington audience. Friday, Aug. 21. Doors at 8 p.m. Nightclub 9:30, 815 V St. NW. Tickets are $35. Call 202-265-0930 or visit www.930.com.
