Funk, soul and jazz-funk reissue specialists Dynamite Cuts are particularly good at offering up seven-inch singles featuring album tracks that have never previously appeared on "45". They're at it again here, delivering a killer seven-inch featuring the much-sampled two-part track that bookends K.C & The Sunshine Band's self-titled, 1975 sophomore LP. "Let It Go (Part 1)" is a low-down Miami funk treat featuring a hot-to-trot-mix of bustling drums, heavy percussion breaks, rousing vocals, fiery (and familiar) horn riffs and impassioned lead vocals. The slightly shorter "part two" mix is an even heavier, vocal-free take that deftly showcases the quality of the band's hip-shaking, rabble-rousing instrumentation.
