There are, of course, great solo performances and recordings within the history of jazz music. But, whether it is Joe Pass interacting with his tapping (Barry Harris likes to say "patting") left foot, or Erroll Garner's vocalized growl that acts as a near-constant background hum, it is the interaction (or, in the case of Bill Evans), the "interplay" that occurs between musicians (or with an imagined other) that imbues jazz with it's vibrancy, it's conversational nature, it's effervescent bounce. A simpatico musical approach is crucial to the success of any improvisational recording, of course, but perhaps especially so in the case of a duo performance. And what a good musical relationship has been established here between Canadian saxophonist PJ Perry and the California-native, pianist Bill Mays.
