Unreleased 1989 hip-hop track by this crew of air force guys in Alaska is "the hardest jam ever."

It's not bad.

Owes a fair bit to PE I guess. They self-released a record as well.

I can imagine this being the one remaining unidentified track in a 96 hour Autechre live stream.

Sounds better than this record!
