John Coltrane's classic quartet of the mid-'60s leaned heavily on McCoy Tyner's rich harmonic imagination and his ability to conjure contemplative moods while keeping the energy high. On albums like A Love Supreme, Tyner's piano accompaniment gave essential support to the saxophonist's most impassioned solos. But Tyner also excelled on lighthearted fare, as on the delicate, swinging sound of Kenny Dorham's composition “Blue Bossa”.
