Free Improv
Free Improv is non-idiomatic spontaneous music that avoids pre-set tunes, jazz changes, steady idiom, and often even stable instrumentation roles. Its sound is built from real-time decisions: table-top guitar crackle, bowed metal, breath tones, prepared piano, split saxophone multiphonics, small percussion, silence, friction, and sudden group pivots. It is less a style of notes than a discipline of attention, where the group invents the form as it hears itself.
History
Free Improv formed in the mid-1960s around British, European, and American musicians who absorbed free jazz and post-Cage experimentalism but wanted a language not bound to swing, blues, or composition. AMM, Derek Bailey, Evan Parker, Spontaneous Music Ensemble, John Stevens, Han Bennink, Misha Mengelberg, Keith Rowe, and later Fred Frith became central figures through clubs, festivals, Incus Records, FMP, and small-label documentation. Its techniques spread into electroacoustic improvisation, reductionism, noise performance, experimental rock, contemporary chamber improvisation, and a culture of recording concerts as unrepeatable compositions.
