From the very first notes on their new release —Sixty and Still Cookin’— the Las Vegas Boneheads lay it all out there. The song is “Al Cohn Tune,” and it is akin to a finely tuned and now rare classic racing car starting its engine and then going for a dizzying spin. There is a propulsion to the playing that captures the essence of jazz music at its most exuberant. From then on, each track continues the exploration with sophistication and daring.
