Louis Prima Jr. loves it when people leave one of his band's shows in a daze. They'd probably arrived, he said, expecting a low-key lounge act. Instead, when they depart, "they describe it as getting hit by a freight train."

"It's non-stop, beginning to end. High energy is an understatement," Prima said in an interview with NJ Advance Media. "We want people up jumping and having as good a time as we are. It's entertainment the way it used to be." Listeners can judge for themselves when Louis Prima Jr and the Witnesses take the stage at New Jersey Performing Arts Center's Chambers Plaza for a free concert Aug. 10.
