From All About Jazz:
John Hollenbeck‘s productivity would be astonishing in its own right, but the uniformly high quality of this high output places the drummer among the top tier of jazz (and not only jazz) musicians. Hollenbeck’s recordings, compositions and performances defy certain expectations. He can be as seriously intellectual as a stereotypically stuffy classical musician, but his music is interlaced with humor and fun. As befits a 21st century drummer, he is rhythmically complex but the music is underlain with a deep groove. He borrows ecumenically from a diversity of musical (including the rhythms of the spoken word) sources and manages to synthesize those varied resources into a coherent creative expression. Some critics have labeled Hollenbeck’s music “post-jazz”: vague but somehow accurate, given that what he does springs fundamentally from jazz, but gives a clear sense of having moved forward from jazz.
