Frippertronics is a tape looping technique used by English guitarist Robert Fripp.[1] It marked the first real-time tape looping device, evolving from a system developed in the electronic music studios of the early 1960s 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.
