Henry Rollins started as the howling, robust frontman of legendary punk band Black Flag. Those who are familiar with Rollins’ vitality and exuberance won’t be disappointed in his spoken-word show. Deceivingly billed as “quintessentially American opinionated editorializing and storytelling,” the show is mostly smart stand-up comedy. The “spoken word” classification often implies a snooze-y presentation of pre-planned, carefully worded poetry, but Rollins’ show couldn’t be more different. He stalks the stage with the same energy and aggression once used for winding up jaded punkers, exploding on the audience with entertaining (and often hilarious) personal stories and tirades. The show is also political: Rollins doesn’t miss any opportunity to express his views and his convincing rants are not without intelligent points — “Dubya” supporters beware.
