Medeski, Martin & Wood at Keswick Theatre

About

For over two decades, the trio’s amalgam of jazz, funk, “avant-noise” and a million other musical currents and impulses has been nearly impossible to classify — and that’s just how they like it. Medeski’s keyboard excursions, Chris Wood’s hard-charging bass lines and Billy Martin’s supple, danceable beats have come to resemble a single organism, moving gracefully between genre-defying compositions and expansive improvisation atop a relentless groove.
