Sessanta

While each group performs their distinctive sets, the musicians continually rotate throughout the night. Primus members join Puscifer’s performance, A Perfect Circle’s bandmates pop up during Primus’ set, and so on. Special guests on the previous performances included Troy Van Leeuwen, James Iha, Sean Lennon, Paz Lenchantin, and Keenan’s TOOL bandmates: Danny Carey, Justin Chancellor, and Adam Jones.
