I'd definitely be curious if Thurston's original master was still somewhere to be transferred, as I too worship
Sonic Death (
proof?), but I'd be much more curious to hear some of the uncirculating shows from that same era. In other words, the full shows that were sampled on
Sonic Death, or just other recordings from '81 thru '83. We're fortunate as fans that so many are "out there", but there's some that probably exist solely in the band's archive. I doubt there's any major "early sonic" release forthcoming but seeing some of them pop up through bandcamp would be a dream.
And don't get me started on Arcadians tapes...
