Best known as engineers for classic albums by Stevie Wonder and the Isley Brothers, Malcolm Cecil and Robert Margouleff were also electronic pioneers. As TONTO's Expanding Head Band, they issued two albums of fanciful synthesizer music. These songs have a compositional sweep that belies their experimental nature, from the bouncing percussive effects and walloping low tones on the aptly titled "Jetsex" to the melodic arpeggios of "Freeflight." The outstanding bonus track "Bittersweet" sounds like an instrumental outtake from a Wonder album. This is what the future sounded like in the early 1970s.
