What more could a world-weary, bop-starved jazzaholic ask for? At Dazzle, a cozy and stylish boîte in Capitol Hill, the management provides a broad array of fresh talent -- local and national -- every week, along with a superb sound system, beautifully made cocktails and excellent saloon food, including a perfect hamburger. From the framed jazz photos on the walls to the chrome martini shakers in the display case, Dazzle's atmosphere reeks of downtown cool. You'll find Prada as well as blue jeans lolling on the living-room couches, but music is the thing. A recent release party for saxophonist Keith Oxman's new CD, Brainstorm, featured some sublime playing, and the club's mid-summer big-band marathon, staged on a Sunday, was sheer bliss -- all twelve hours of it.
