For the first time, two of the Triangle's most boundary-melting jazz combos will share the bill at Casbah. Everything old is new again for Peter Lamb & the Wolves, a sax-led quintet with '60s cool and a Latin tinge. Lamb's arrangements of Ray Charles, Nat Cole, Tom Waits and Astor Piazzolla throw the classics for a toe-tapping loop-de-loop. Meanwhile, beautiful intensity exudes from the "chambersoul" of Shana Tucker, a singer-songwriter whose main instrument is the cello. Her original gumbo of jazz, folk and R&B evokes the spirit of Bill Withers and Esperanza Spalding. Tucker and her quartet play first at 8 p.m., followed by Lamb and his band around 9:30. "We want to introduce our respective fans to a double dose of good music," Tucker says, while Lamb adds that "we'll be doing some tunes together throughout the night." For a kinetic evening of swoon and swing, come as you are—and leave transformed. —Sylvia Pfeiffenberger
