Tim Minchin was one of the performers at the Reason Rally, and I'm sorry to say that I wasn't all that familiar with his stuff prior to hearing him last weekend. He is extremely talented, and smart as a whip. Check out this video of probably his most well known work, a beat poem entitled "Storm." Great stuff.
Here is the youtube link to the video, since blogger limits video uploads to 100mb, and this one was 112. Bummer.
