Frippertronics

Frippertronics is a system of tape loops created by Brian Eno and Robert Fripp. The system consists of two tape recorders with a single loop of tape going between the two machines. This allows a performer to record on one of the two recorders and play it back on the second, after which the recorded piece of tape makes its way to the first recorder and is recorded onto again.

Using Frippertronics, Fripp was able to play many sounds layered on top of each other on the single loop of tape. This led to several seminal recordings, most famous of which is No Pussyfooting, the first album in which the system was used.
