Coffey was raised on Detroit’s west side and played guitar as a child, developing an early love of jazz, country, and the blues.
By his teenage years, he was playing clubs and sampling Detroit’s many musical styles, fusing Motown, rock & roll, R&B, and jazz into his own signature sound.
From there, Coffey signed on with Motown’s Funk Brothers in the late 1960s just as the label was moving from polished soul to funkier, more socially conscious material.
He can be heard playing guitar riffs on The Temptations’ “Ball of Confusion,” “Psychedelic Shack,” and “Cloud Nine” – songs full of trippy psychedelic effects like fuzz tones, distortion, and the wah-wah pedal that defined Motown for an entire new decade and brought a real countercultural vibe that would propel soul music towards funk and hip-hop.
