Recently I was cleaning up / deleting old mails, and notice Keith's mail that was telling about the unreleased Taint material he was intending to mail me. Those were original 4-track tapes running in regular and double speed and for many years he had no gear to make transfers. He died so suddenly, that plan of sending those tapes never realized and unfortunately gone. I know there are couple people who do have (probably) unreleased stuff / alternative versions. Guys who ran labels and meant to do things and final version of album is missing some tracks. Of course, those were probably cut away for reason.
