Yes, that's a vibraphone buzzing like an overheated tea kettle on "Pretty Brown Skin," the opening track of Roy Ayers' first album with his fusion concept band, Ubiquity. The sound—Ayers ran his vibes through a distortion pedal for a scuzzy, surprising, and singular effect—announced his arrival on Polydor and his further push into the psychedelia and prog rock budding alongside him in 1970. Even his take on Burt Bacharach's "Raindrops Keep Falling on My Head" veers from genteel post-bop jazz into bass-driven funk.
