"Night in Tunisia is terrific; Halperin's sax is urgent and slightly fractured, at times almost like a human voice. "Witch Hunt is another gem, with Halperin both piercing and lyrical, his sax emitting a series of bleeps and twists and flutters. "Spanish Castle Magic has a great groove that stays true to the Hendrix sound and at the same time takes the music to the next level.

One of the CD's unique features is two takes of "Don't Explain, one each on tenor and soprano. The tenor take sticks close to the melody and brings out the song's heartbreak and melancholy, while the soprano highlights Halperin's conceptual gifts. The two takes offer fascinating insight into jazz's pliability.

Halperin is exciting to listen to because you're never quite sure where he's going next. In the liner notes CIMP producer Bob Rusch muses as to whether Halperin's work is outside in or inside out: it's that quality exactly which makes it so satisfying.
