Some days Ward 22 Alderman Greg Morehead is banging out legislation. Some days he’s banging on drums as part of the band DangerZone.

Morehead is holding auditions at Caffe Bottega at 6 p.m. today, looking for another drummer to play with DangerZone when the band performs March 1 with Ludacris on the “Late Show with David Letterman.”

“I’m trying to expose somebody from New Haven,” Morehead said.

And it won’t just be a one-time gig for whoever wins the spot: While Morehead will continue as drummer, the new member of the band will stay on as a percussionist.

Anyone can audition, Morehead said, and he’ll be auditioning approximately 75 people.

DangerZone and Ludacris are also performing next month on “The Ellen Degeneres Show,” “Lopez Tonight” and “Jimmy Kimmel Live!”
