Friend of AMN Lyn Horton writes about writing:
Free improvisation employs broadly accepted ensembles of instruments, speaking a language that is sometimes foreign to the instruments; but also within this music is used, among countless others, the doson gouni, the kora, the shenai, the cello, the violin, the oud, the djembe, accordion, synthesizers, amplifiers, samples, vocals, spoons, mouth-harps. Box drums. Table tops. Stages. And instruments still to be invented.
