It is, put simply, one of the very greatest modern jazz albums. Play it back to back with the fabled Kind of Blue and to an entirely unprejudiced audience, if you can find one, and it yields not a whit in quality or musical depth. Miles was beginning to explore the deeper implications of modality, which freed jazz from the tyranny, as it had begun to seem, of harmonic “changes”. Pianist Red Garland’s studio walk-out made things easier for the leader. Working without the piano’s fingerwagging in the corner was liberating.
