Frippertronics

Frippertronics is a tape looping technique used by the English guitarist Robert Fripp. It marked the first real-time tape looping device, evolving from a system developed in the electronic music studios of the 1960s by composers including 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 digital looper units.
