Few tourists walking by on Grant Street in San Francisco’s North Beach district would recognize the stringy-haired regular sitting at a cafe table and swilling espresso, but to locals, the sight of Jefferson Airplane founder Paul Kanter is unmistakable. Kanter turns 70 this week, and to celebrate, 142 Throckmorton is hosting a two-day, all-star soiree with Jefferson Starship headlining. Guests throughout the residency include members of Hot Buttered Rum, Big Brother and the Holding Company, the Mother Hips, Prairie Prince, Slick Aguilar, Pete Sears, David Freiberg and many more. Join the party on Saturday and Sunday, March 19 and 20, at 142 Throckmorton. 142 Throckmorton, Mill Valley. 8pm. $45–$125. 415.383.9600.
