“While Zemelman possesses a lovely touch and fertile harmonic imagination, what stands out most on One Way Or Another is the probing lyricism that undergirds his group concept.  He gives his formidable collaborators plenty of space, but the improvisation is always tightly bound to the melodic line.  The resulting music is playful, tender, celebratory and consistently engaging, a rare project that compels a second, third and fourth spin.” -Andy Gilbert, SF/bay area jazz critic, on Dan Z’s debut CD One Way or Another.
