Time to monetize your Barrett tapes

[masterjedi]

I've never heard of these unsurfaced versions of It's All Too Much, is there any hint as to what they might be?

This list is fairly accurate, other than nothing on Vigotone should be listed as core (they just EQ'd and poorly noise reduced the exact same transfer as Roaring Mouse)

I've always wondered which of the various Barrett Tapes boots was the one closest and truest to the source. Is it the Roaring Mouse/Geritol releases?

yes.

I guess that's why they called it "True Masters" from Roaring Mouse/Geritol
