The Bop Shop celebrated “guitar month” in February, and the picks continue to fly into March with the arrival of Bob Ferrazza, who brings his Cleveland-based quartet (sax included, no piano) in for one night. You can think of Ferrazza as the “strong and silent” type–or, if not silent, then at least diffident. A solid player in the postbop vein, he doesn’t waste a lot of notes; his well-crafted solos, as well as his unpretentious compositions, trade flamboyance for straightforward communication and unhurried swing. Ferrazza’s appearance could be seen as just another installment in the Bop Shop’s “Ohio fretmen” series (last month featured Joshua Breakstone, who lives in Cincy). But that whimsy belies the fact that the Bop Shop, alone among Chicago jazz clubs, has made a point of importing regional artists–from not only Ohio, but also Detroit, Milwaukee, Madison, etc–who would never otherwise got to town. As the de facto capital of the midwest, Chicago deserves to hear the region’s best musicians just as much as they deserve to play here–and almost as much as the Bop Shop deserves credit for widening its net. Saturday, Bop Shop, 1807 W. Division; 235-3232.
