in 1973. During this period he also worked with Van der Graaf Generator, playing on the 1970 album H to He, Who Am the Only One, and in 1971, on Pawn Hearts. He produced Matching Mole's Matching Mole's Little Red Record in 1972. Prior to forming the Larks-era KC, he collaborated on a spoken-word album with a woman he described as "a witch", but the resulting Robert Fripp & Walli Elmlark: The Cosmic Children of Rock was never officially released. With Brian Eno, Fripp recorded (No Pussyfooting) in 1972, and Evening Star in 1974. These experimented with several avant-garde musical techniques that were new to rock. On "The Heavenly Music Corporation" from No Pussyfooting, Fripp used a tape delay system using two modified Revox A77 reel-to-reel tape machines for the first time. The technique went on to play a central role in Fripp's later work, and became known as "Frippertronics". In 1973, Fripp performed the guitar solo on "Baby's on Fire", perhaps the best-known track on Eno's solo debut Here Come the Warm Jets. In 1975, Fripp and Brian Eno played live shows in Europe, and Fripp also contributed guitar solos to Eno's landmark album Another Green World. Fripp started what was intended as a permanent sabbatical from his career in 1975, during which he cultivated an interest in the teachings of Gurdjieff via J. G. Bennett (studies which would later be influential in his work with Guitar Craft). He returned to musical work as a studio guitarist on Peter Gabriel's first self-titled album in 1976, released the following year. Fripp toured with Gabriel to support the album, but remained out of sight (either in the wings or behind a curtain) and used the pseudonym "Dusty Rhodes". He produced and played on Gabriel's second album in 1978. "Robert is particularly skilful at keeping things fresh, and I like that a lot," Gabriel enthused. "I was very interested in Robert's experimental side; that corresponded exactly to what I wanted to do on this second record… There are two (Fripp) solos: one on 'On the Air' and the other on 'White Shadow'. And then he plays on 'Exposure'. He gives the colour to this piece, being fifty per cent responsible for its construction. And he also plays classical guitar here and there. He's a musician I admire a lot, because he's one of the only ones to mix discipline and madness with
