The Kingston jazz scene is heating up in the dead of winter, and Midtown is ground zero. Not only can you occasionally catch jazz at Tilda’s Kitchen, The Lace Mill and Tubby’s, but Chromatic Studios hosts a killer open jazz jam in an intimate setting. The musicianship on hand is off the charts, and the night is led by a full five-piece house band. Acoustic instruments and singers are always welcome. Suggested donation is $10 for listeners, $5 for musicians. Could this be the start of the jazzification of Kingston?
