On top of the 4,000 cassettes of my own that reside at the archive, I also have other collections– I have over 500 punk cassettes from Jason Ross, about 100 from Dal Basi, A lot from Brian McKenna, and a couple hundred from my friend Anonymous. He taped with a Sony WMD6C Pro Walkman back in the late 80s and was able to get some nice results from the deck along with a Sony ECM909 mic.
He told me that this was one of the loudest shows he had ever attended, and it still sounds pretty damned good. This is a transfer from his master tape.
