Tonto's Expanding Head Band was a British-American electronic music duo consisting of Malcolm Cecil and Robert Margouleff. Despite releasing only two albums in the early 1970s, the duo were influential in the development of electronic music and helped bring the synthesizer to the mainstream through session and production work for other musicians (most notably Stevie Wonder[1][2]) and extensive commercial advertising work.
