First released in 1974 during his early Polygram run, Change Up The Groove finds Roy Ayers Ubiquity deep in the pocket between jazz finesse and funk muscle. Ayers' vibraphone work threads through arrangements driven by Bernard Purdie's precision drumming, with strings adding a stealthier warmth about the edges. The set moves from the slick, percussive strut of the title track to the supple swing of 'Sensitize', a cover of Stevie Wonder's 'Don't You Worry 'Bout A Thing', and the cinematic 'Mash Theme'. His version of 'Feel Like Makin' Love' hums with soft electric glow, while 'The Boogie Back' rides a breakbeat that's fed countless hip-hop samples. This 2025 Vampisoul reissue comes on LP, restoring a key chapter in Ayers' shift toward 70s funk.
