occasional lurker, first-time poster, this comment made me register and chime in with my two cents:
to each their own, I heard this for the first time yesterday, and barely made it all the way through. I can say that it's my least favorite AMM session without question. Very very ordinary and dull, you wouldn't know it was AMM if it didn't say so on the front cover (it barely is, it's the Gare/Prevost duo version, during the period when Rowe and Cardew had left the band). either way, hardly representative of AMM, for better or for worse.
if you're looking for a different sounding free jazz/improv reissue from the early seventies, I enjoyed this one that came out last week for the first time much, much more than the Anomalous AMM (available through Forced Exposure):
