The super homie and king of westcoast underground updates on discogs, KaliYuga Pro and I have been discussing this Emanon - Unreleased 90 Minute Tape we both happen to have. Neither of us know any of the history behind this, who released it or when it came out. We both obtained it from different sources and our copies are of differing quality. Here is a cassette rip of my copy.
