Primus’ Les Claypool has been added to a December 6 benefit at Mill Valley, CA’s 142 Throckmorton Theatre. As previously reported, the fourth annual event will benefit the children of the Peruvian orphanage, Casa de Milagros. This year’s benefit will also support the Haitian Relief Organization J/P HRO. Previously confirmed guests include: Bob Weir, Jackie Greene, Primus’ Jay Lane, ALO’s Lebo & Steve Adams, and James Nash of TheWaybacks.

Claypool is expected to perform with his new Duo De Twang project. Since he also plays with Lane in Primus and has collaborated with Weir over the years, one can expect some additional collaborations.
