This is one of those rare albums that demands to be actively listened to from start to finish. To me, it's one big piece of music that flows perfectly from moment to moment. It's almost impossible to put on a song or two for casual listening. The album still defies categorization 35 years down the road. Great choice.
P.S. It's an over simplification for sure, but Michael Shrieve can lock up with a latin rhythm section like no one else. He's so sympathetic, always listening. Probably my favorite drummer period.
