FROM THE EAST BAY EXPRESS Seldom do homegrown comedians have as much personal magnetism or shrewd observations as W. Kamau Bell, who is best known for his ever-evolving one-man show, The W. Kamau Bell Curve. Bell and Kevin Avery used to have a weekly radio spot on Live 105 called Siskel and Negro, which they mostly dedicated to film reviews — with some pop-culture miscellany mixed in. At this point, though, Bell has busied himself with an ongoing critique of race politics, integration, sanctimoniousness, silent hypocrisy, and glaring inequity in the so-called Obama Age. Bell constantly recobbles his material to stay on top of the news cycle, so it's a different show from month to month. This New Year's Eve he'll revisit the big stories from 2009, and examine pop culture from a racy angle. Aptly titled "Laughter Against the Machine," Bell's night of "guerilla comedy" also features the equally incisive Hari Kondabolu, and local favorite Nato Green.
