I had both of these on lp and sold them to finance my AEC box - I made cdrs of the vinyl and wonder if this issue is derived from "needle drops". FWIW, my discs combined time out over 80 minutes.
I discovered the tape while preparing the cd reissue of the '60s AACM series for Delmark. The first couple of minutes are "warming up" but the rest is fascinating. I sent a copy to Muhal's wife. Rights have not been cleared.
Not my intention. Collecting large quantities of recordings, posting regularly on music boards, researching musicians lives and habits, etc. qualify as elements of a "life plan".
