Frippertronics is a specific tape looping technique used by Robert Fripp. It evolved from a system of tape looping originally developed in the electronic music studios of the early 1960s that was first used by composers Terry Riley and Pauline Oliveros and made popular through its use in ambient music by composer Brian Eno, as on his album Discreet Music (1975). The effect is now routinely found in many commercial loop station guitar digital effects boxes such as the Boss RC-3.
Frippertronics is an analogue delay system consisting of two side-by-side reel-to-reel tape recorders. The machines are configured so that the tape travels from the supply reel of the first machine to the take-up reel of the second, allowing sound recorded by the first machine to be played back later on the second. The audio of the second machine is routed back to the first, causing the delayed signal to repeat while new audio is mixed in with it. The amount of delay (usually three to five seconds) is controlled by increasing or reducing the distance between the machines.
Fripp used this technique to dynamically create recordings containing layer upon layer of electric guitar sounds in a real time fashion. An added advantage was that, by nature of the technique, the complete performances were recorded in their entirety on the original looped tape.
The (No Pussyfooting) recordings
Fripp first used the technique while recording in Brian Eno's home studio, combining guitar performance with 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. A subsequent 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 editing were done.
This delay system was first used in live situations for a short European Fripp & Eno tour in May–June 1975, with the 28 May 1975 concert at the Paris Olympia Theatre being bootlegged as Air Structures (in 2010 the concert was officially released as a download, with Eno's original backing loops).
After returning from this tour Eno released his own version of the open loop tape system with Discreet Music (1975), one side of which (the title track, recorded 9.5.75) utilizes what would later become known, somewhat erroneously, as "Frippertronics." 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."
Frippertronics and its types
The term "Frippertronics" was later coined to label a version of this system that Fripp felt he could operate by himself as a solo performer. In what he called "Pure Frippertronics", Fripp created the loops in real time with no additional editing. Included was the method of rewinding the recorded tape, to be played back while Fripp would improvise a guitar solo on top of it.
Fripp used this type of Frippertronics to perform live solo concerts in small, informal venues. It allowed him to be what he referred to as a "small, mobile, intelligent unit", as opposed to being part of a massive rock concert touring company. One such show was in a room at Faunce House at Brown University, in a venue built to be a tiered classroom.
Only one and a half albums of Pure Frippertronics were officially produced: Side A of an album with two names God Save the Queen/Under Heavy Manners in 1980 (God Save The Queen was the pure Frippertronics side, containing three compositions; Red Two Scorer, God Save The Queen, and 1983.) and Let the Power Fall in 1981. Let The Power Fall takes up where God Save The Queen left off, with works entitled 1984, 1985, 1986, 1987, 1988 and 1989. Marriagemusic was the B side of a League Of Gentlemen single; it is perhaps the longest single side ever produced, clocking in at over 11 minutes. Additionally Fripp made available an audience bootleg recording of a live Frippertronics concert (recorded at The Sound Warehouse in Chicago, Illinois, on 18 June 1979) as an Mp3 download, available on the Discipline Global Mobile web page. There is also a 2-LP bootleg of live Frippertronics entitled Pleasures In Pieces recorded at The Kitchen in New York City on 5 February 1978, containing five tracks (in order of appearance; The Second, The First, The Third, The Fourth, The Fifth, ranging from almost 7 minutes to over 24 minutes. The titles of the pieces are most certainly not given by Fripp. This bootleg has also been issued by persons unknown as a single CD. It is most likely a CD-R recording of the vinyl 2-LP set. Of course Pleasures In Pieces was not and is not authorized by Fripp, and most likely he would excoriate anyone involved with making those recordings available to the public. However, the Sound Warehouse recording was issued by Fripp as an Mp3 file through his DGM web page, though he makes clear that the recording is an audience bootleg and was not originally authorized by him.
Frippertronics was also used by Fripp in more conventional rock recordings, replacing what could be viewed as musical parts normally served by orchestral backing. He referred to this as "Applied Frippertronics". Several of Fripp's albums, as well as albums by Peter Gabriel, David Bowie, Daryl Hall, and The Roches, featured this usage. Also, Side B of God Save the Queen/Under Heavy Manners included what Fripp termed "Discotronics", mixing Frippertronics and a disco-style rhythm section.
