Fusion, lest we forget, spawned both new age and smooth jazz. Guitarist Lee Ritenour’s Rhythm Sessions is proof. Alongside its ample fusion credentials (including two dozen accomplished players, among them Marcus Miller and Stanley Clarke), it’s loaded with the glossy production and vampy lite-funk one expects to hear while on hold.

This is apparent on his riffy tune “July,” during which electric bassist Melvin Davis and drummer Sonny Emory work out a canned groove; Ritenour’s liquid, imaginative electric solo makes short work of the piece. He also adds acoustic sweetness to “Rose Pedals” and “Children’s Song #1” (featuring piano work by its composer, Chick Corea), and brings life to the repetitive South African funk of “The Village,” pairing his high-end lead with George Duke’s Moog synthesizer.
