Frippertronics is a live music technique developed by guitarist Robert Fripp in the late 1970s. It involves the use of two tape recorders to create a looped sound, allowing for real-time layering of guitar melodies and effects. This method produces a rich, evolving soundscape that can be both meditative and complex. The technique gained popularity in the progressive rock and ambient music scenes, influencing various artists and genres. Frippertronics showcases the possibilities of live improvisation and sound manipulation, making it a unique form of musical expression that continues to inspire musicians today.
