Police have issued an arrest warrant for Joshua Wilkes of The Legendary Shack Shakers.

The arrest warrant says Wilkes was performing Friday night when he exposed his genitals to a few hundred teens and adults in the audience.

Ben Cissell, a representatives for the club, says it was the group’s first – and last – performance at Rocketown.

The group was opening for the ’90s punk rock band Rancid.

Rocketown says it screens the bands that play there to make sure they are appropriate.

A representative of the Legendary Shack Shakers was not immediately available for comment.
