HarS
HarS's "Sound Chronicles" is an ongoing series of relatively short montages (started early 2000) using as material, pretty much exclusively, audio fragments taken from a large collection of lo-fi, and mainly monophonic, field recordings: sonic 'snapshots' made with cheap portable cassette machines and a lapel microphone between the late 1970's and now, pretty much all over the world.
