Steve Kimock is currently in the midst of his most extensive national tour in a number of years. For this run of shows, Kimock’s steady band consists of keyboardist Bernie Worrell and drummer Wally Ingram, with Tea Leaf Green’s Reed Mathis and former Gov’t Mule member Andy Hess splitting bass duties on different legs of the tour.

On Friday, Kimock performed at New York’s Brooklyn Bowl and invited out a number of additional musicians. Drummer John Morgan Kimock, the guitarist’s son and sometimes bandmate, performed throughout the entire two-set show while guitarist Bobby Bryan sat in on guitar and vocals at the end of their first set for “Talk About it Blues,” “Standing on Shaky Ground” and “Take Me to the River.” Though Mathis was the evening’s scheduled bassist, Hess, who lives in the area, also sat in for a few songs throughout the night.

A few more surprising guests joined Kimock during his second set. Blues Traveler frontman John Popper, who was spotted watching the show sidestage with Rolling Stones saxophonist Bobby Keys, emerged at the start of set two for “TLC,” “You’re the One” and “Many Rivers to Cross.” Bryan then returned with violist Todd Reynolds—one of Steve Reich and Bang on a Can’s steady collaborators—for “Family Tree” and “Red Hot Mama.” The latter song also included a tease of Jethro Tull’s “Aqualung.”

Kimock and his band will perform at Bostons, MA’s Middle East this evening. Hess is slated to play bass. The guitarist has also added a series of West Coast dates and a trip to Japan to his July itinerary.
