A National Public Radio affiliate by day, KJZZ transforms into a chilled-out jazz station at the workweek witching hour of 7 p.m. Dominating the night is "Acoustic Jazz," a mix of jazz classics and newer traditional tracks, with silky-voiced local diva Blaise Lantana hosting the earlier segment and Paul Anderson, Michele Robins, Steve Conrad and Phil Pollard taking over in later slots. There's no time for the blues until the weekend, but two locally produced shows, Drew Verbis' Blues and Beyond, and Rhythm Room impresario Bob Corritore's Those Lowdown Blues (now in its 20th year), are always worth the wait.
