I recall R.Grief LP on RRR has always been very cheap and easy to get. And besides that, good on pressing/sound/covers. Its been long since I listened it, but by the gut feeling, I would recommend that one.
Indeed, plenty of american sound artists who in past crossed over to "noise scene". Obscure sound collages of Wiggins, nice experiemental ambient of Dimuzio, minimalistic feedback manipulations of Archane Device, experimental industrial sounds of P.Children, I guess PBK is mentioned on this board by myself? Or if not, it should! And these are just stuff from RRR old catalogue.
