An intriguing quintet will come together tonight in San Francisco for “an epic night of funked up, ground breaking soul booty music.” Warren Haynes Band bassist Ron Johnson will be joined by Garaj Mahal keyboard player Eric Levy and Jazz Mafia drummer Joe Bagale along with guitarists Will Bernard and Dan Lebowitz at the Boom Boom Room. Lebowitz, whose ALO is taking New Year’s off, will return to the club on December 31 for what is billed as LEBO & Friends. Following this set, a late night party boasting Big Light—featuring ALO bassist Steve Adams—and the SF Gramble will take place. This jam session will not only feature the evening’s players but a variety of musicians in the Bay Area for New Year’s Eve.
