Query: Nice grooves,

This album really focuses on Billy Martin's street beats and the sonic character of Medeski's organ. While the instrumentation is stripped down compared to MMW, the grooves are tight and creative and nicely accented with effects. The album has a nice old school vibe to it, like the warm glow of a vacuum tube, and a lot of diversity among styles. My faves on the album are Crustaceatron, Bonfa and Miss Teardrop
