What does it mean for Seattle's most important, most traditional, and most international jazz establishment to invite Choklate, a local and emerging neosoul singer, to perform for two nights? It means something big is happening. It means Choklate's world is expanding beyond the limits of neosoul and hiphop, into the immaculate realm of America's classical music. For this show, Choklate will perform with three members of Industrial Revelation. (Dimitriou's Jazz Alley, 2033 Sixth Ave, 441-9729. 7:30 pm, $20.50, all ages, also Tues March 4.)
