Nothing if not dutiful, I filled in one of the gaps in my AMM collection, pulling the trigger and buying this compilation on e-bay for an ungodly price. It arrived this afternoon.

The AMM track (on first listen, the only thing of any interest) is from 4/20/67, a performance that was broadcast on the BBC. About 15 minutes long, it's a pretty fascinating piece, one I'll have to listen to much more, obviously. Rowe lets loose in furious fashion toward the end of the track, one of the only things I've heard from this period in which (imho) you can hear definite linkage to some of his harsher work from 30+ years hence.
