Le Jazz Hot Quartet plays French Gypsy Jazz, naming themselves after (and playing some of the repertoire of) the pioneering French combo of guitarist Django Reinhardt and violinist Stéphane Grappelli and their Quintette du Hot Club du France. The string ensemble (Hot Club of San Francisco is their touring name) has been playing these tunes for 11 years, and they make a pair of appearances at Yoshi's San Francisco in October, among other gigs. But on August 18, they bring Paris to Palo Alto, playing a set for free at the Stanford Shopping Center. Sure, there's an American swing to this group, but that's all to the good. Bring your dancing shoes.
