Introduced by smooth-talking host Gerry B, Stevie Wonder's 50-minute 1972 live set for PSB show Soul! was never broadcast in the UK. It documents a period when Wonder's creativity was so rampant that nothing Soul!'s producers threw at him could crush it: not a contemporary dance interpretation of You And I, nor a surfeit of low-budget psychedelic effects, nor the deadly patter of Gerry B ("You used to be Little Stevie Wonder. What was it like being Little Stevie Wonder?"). He shifts between My Cherie Amour and Dylan's Blowin' in the Wind with breathtaking slickness, interpolates Superwoman with passages of intricate afro-funk and ends a frantic Uptight with a wall of dive-bombing synthesized noise. Meanwhile the studio audience provide delightful period detail: when Wonder plays a vocorder, they gasp in awe, as if he's just donned a jet pack and flown around the studio.
