Recently making his film debut opposite Kevin Hart in The Wedding Ringer and winning Howard Stern’s “Kill or Be Killed” comedy competition, Colin Kane is known for his insult comedy tactic. Between his in-your-face delivery and off-the-cuff crowd work, Kane’s work has proven contagious across the country; sex, relationships and race are fair game and those who sit in the front row… Well, you’re brave souls. For a raucous evening with a raw performer, catch Kane tonight at 7:30 at the Improv, where he performs through Saturday. Tickets are $17. (Immerman)
