Swingin' Party is a reflection of the man who made it. Barney Kessel's joy in life and living comes through in his playing here and in his interaction with the trio of young men who were his colleagues in the Barney Kessel quartet for a year or so as jazz moved from the 1950s into the Sixties. It was a time of change and experimentation, and Kessel was interested in the fresh winds blowing through jazz. As he makes plain in his album notes, he was all in favor of jazz being free. He was not in favor of its being free of swing, so he concentrated on investing these six performances with the rhythmic values that he felt were at the heart of the music. Pianist Marvin Jenkins and drummer Ron Lundberg later became inactive in jazz, but bassist Gary Peacock was already a trailblazer on his instrument and has endured as one of the instrument's giants.
