Editing Frippertronics (section)

==The ''(No Pussyfooting)'' recordings==
Fripp had first used the technique when Brian Eno introduced him to it in Eno's home studio, combining Fripp's guitar performance with the two-machine tape delay, on the 21-minute piece "The Heavenly Music Corporation" recorded on 8 September 1972 and released on the [[Fripp & Eno]] album ''[[(No Pussyfooting)]]'' in 1973.<ref name="Prendergast">{{cite book |title=[[The Ambient Century: From Mahler to Trance – The Evolution of Sound in the Electronic Age]] |last=Prendergast |first=Mark |year=2001 |publisher=Bloomsbury Publishing |pages=[https://archive.org/details/ambientcenturyfr00pren_0/page/119 119] |isbn=1-58234-134-6 }}</ref> A subsequent Fripp & Eno album, ''[[Evening Star (Fripp & Eno album)|Evening Star]]'', was released in 1975. These recordings were not purely tape loops however, since some after-the-fact processing, [[overdubbing]], and [[audio engineering|editing]] were done.

The delay system was first used in live situations for a short European Fripp & Eno tour in May–June 1975 promoting ''Evening Star'', with the 28 May 1975 concert at the [[Paris]] [[Olympia (Paris)|Olympia Theatre]] being bootlegged as ''Air Structures'' (in 2011 the concert was officially released as a download, along with Eno's original backing loops).<ref>{{cite web |url=http://www.dgmlive.com/archive.htm?&show=1340 |title=Fripp & Eno |website=dgmlive.com |date=28 May 1975 |accessdate=5 May 2014 |url-status=dead |archiveurl=https://web.archive.org/web/20140505200040/http://www.dgmlive.com/archive.htm?&show=1340 |archivedate=5 May 2014 }}</ref>

After returning from this tour Eno released his own version of the open loop tape system with ''[[Discreet Music]]'' (1975), one side of which features looping.  Eno mentions in the liner notes that "here is the long delay echo system with which I have experimented since I became aware of the musical possibilities of tape recorders in 1964."<ref>Liner notes to "Discreet Music".</ref>
