This arrived while I was away. I have another LP from the same run at the Keystone that I love ('Classics') and first impressions are this is just as good. Fantastic band with Bobby Hutcherson and Joe Henderson - you can't go wrong really. I even like the electric bass playing of Larry Klein. Nice stretched out 10 min versions of each tune by a band that have been playing together a while. Jazz from this period is a bit of a minefield but this is great.
Kudos to The Keystone for installing a decent recording rig - it looks like quite a number of LPs resulted while the club was open.
