Chkiantz was a staff engineer at Olympic Studios at the same time that the Jimi Hendrix Experience was recording Axis: Bold As Love.
During the session with the Small Faces, Chkiantz engineered the song "Green Circles", which represented the first use of mono flanging on a pop record; he subsequently perfected the technique on their landmark 1967 single "Itchycoo Park".
[1] Upon hearing the result, Jimi Hendrix and his engineer, Eddie Kramer applied Chkiantz's concepts, creating stereo phasing on the songs "Bold As Love" and "Little Wing".
"[2] Hendrix used to refer to George Chkiantz and Eddie Kramer's stereo phasing technique as the sound he had been "hearing in his dreams".
In the late 1960s and throughout the 1970s, he worked with The Soft Machine, Savoy Brown, Ten Years After, King Crimson and Led Zeppelin.
