Primus rocks the Hard Rock Hotel in Las Vegas with Clutch in September

Primus lead singer Les Claypool loved the movie “Charlie and the Chocolate Factory” so much that he hosted a Willy Wonka-themed Primus concert on New Year’s Eve in 2013. Since then, he reunited his Primus lineup with Larry LaLonde and Tim Alexander to form Primus and the Chocolate Factory with The Fungi Ensemble.

The group heads to The Joint at the Hard Rock Hotel with special guest Clutch on Friday, Sept. 4.

The Grammy-nominated experimental rock group released its self-titled album last October.

“The whole thing just unfolded,” says Claypool in a press statement. “It was a very easy and pleasant project. It wasn’t like we sat and scratched our heads... every song was all wrapped around how I would interpret the vocals, for the most part, because that was the most challenging thing.”

Primus is probably best known for the theme for “South Park, but songs such as “Jerry Was a Race Car Driver” and “My Name Is Mud” have kept the band in the limelight.

Maryland heavy rockers Clutch share Primus’ love of boundary-pushing music. The group’s music has achieved notable ranks on the iTunes and Billboard charts, and their album Earth Rocker was awarded “Album of The Year” in 2013 by Metal Hammer magazine and garnered a Top 10 spot on Rolling Stone’s “20 Best Metal Albums of 2013.”

Tickets start at $42.50 and go on sale Friday, May 15.
