This past weekend's AltCom seemed to me a great success. I attended almost every show, and there were a couple of packed houses, most notably for the Steamy Bohemians and Jerkus Circus at the Burren and at the Somerville Theatre for the early show headlined by Janeane Garofalo.
The Bostonist was there, too, and got some video of the performances. If you didn't go, here's a bit of what you missed:
Jamie Kilstein at the Somerville Theatre.
Leo Allen at the Somerville Theatre.
Rob Riggle at the Somerville Theatre, plus interview.
Eugene Mirman defines alternative comedy, plus interview.
And here's the Bostonist's review of Garofalo show.
