Primus have announced the details for their New Year’s Eve show. Primus will be teaming up with the Frog Brigade Ensemble for a performance at the Fox Theater in Oakland on December 31. The special show—dubbed An Evening with Primus & The Chocolate Factory—will take fans on a “psychedelic and whimsical journey through the music of Willy Wonka & the Chocolate Factory.

Pre-sale tickets for the concert will go on sale today at 10am PT for those with the passcode “athletics.” Everyone that orders a pre-sale ticket will be eligible to win one of five “Golden Tickets,” which earn the winner a signed poster, event T-shirt, a bucketful of candy and a tour of Primus’ backstage (with a friend).

As previously reported, original Primus drummer Tim “Herb” Alexander will be rejoining the band this fall. The group’s current drummer, Jay Lane, will be returning to RatDog with Bob Weir, as well as playing with his new band, Jay’s Happy Sunshine Burger Joint.
