They first appeared in 2013, but for the last year rock and jazz group Incidental Animals have been all too quiet. The group consists of members of the String Cheese Incident, the Trey Anastasio Band and ALO, and now they’ve awakened from hibernation for a West Coast weekend tour that includes stops in San Rafael and Petaluma. First, the band boogies with Phil Lesh and friends on Thursday, May 7, then play a set on their own on Friday, May 8, at Terrapin Crossroads (100 Yacht Club Drive, San Rafael. 8pm. 415.524.2773). On Sunday, May 10, they head north and kick it with the Highway Poets at the Mystic Theatre (23 Petaluma Blvd. N., Petaluma. 9:30pm. $26–$28. 707.765.2121).
