Jonathan Halper has been played on NTS shows including Lucifer Over LA, with Leaving My Old Life Behind first played on 24 August 2015.

Jonathan Halper is the virtually anonymous architect of the atmospheric and stirringly post-modern soundtrack to notable avant-garde filmmaker Kenneth Anger's 1966 edit of the 1949 short film, "Puce Moment". The six and a half minute contribution contains two distinct songs, "Leaving My Old Life Behind" and "I Am A Hermit", and reflects a stirring fusion of traditional folk sensibilities and airy, psychedelic musical experimentation; shockingly these two songs represent Halper's lone extant contributions to the popular musical canon. The enigmatic Halper is rumored to have retired to a monastery shortly after the recording of the aforementioned material and even these two tracks exist only in direct audio rips from the film.
