Master drummer Jack DeJohnette (also an alum of Miles Davis' band) personally selected and sequenced the tracks on this collection, with an ear for Tony's strengths as a drummer, composer, and improvising musician. This means a bare minimum of vocals and the sort of tracks that may not have been chosen by a "suit" or a hipster. The music is characterized by structural dynamism (often somewhat asymmetric,) a distinct minor-key feel provided by McLaughlin's guitar and Young's alternately eerie and assaultive organ parts, and a massive wall of syncopation that can never be pinned down to a recurring motif for very long. Those who want most of the best of this period in Williams' career should invest in this disc and spare themselves the expense (and the hideous vocals)of the anthology.
