REAL VOCAL STRING QUARTET, Real Vocal String Quartet (Flower Note): (3 stars out of 5)

Cello, viola, two violins, four voices: that’s the basic setup for this Bay Area quartet that elegantly blends chamber music with African and Appalachian folk rhythms. The unexpected mix of influences keeps things pleasingly fresh, whether assaying Brazilian jazz (“Fonte Abandonada-Passatempo”), a cinematic take on Paul Simon’s “Night Game” or one of violinist Irene Sazer’s eclectic compositions. Should appeal to fans of Crooked Still and Sazer’s old band Turtle Island String Quartet. At Bootleg Theatre in LA Sunday. rvsq.com.
