Though not a Jazz Messengers album, I somehow like Bluesiana Triangle, where Blakey participated as a drummer. Since it was recorded just before his death, you don't really feel much power anymore, but it has a rich, savory flavor. I think his strength wasn't power, but rather his excellent taste. He plays piano and sings too.  

It's similar to the first volume, about as good, too. I am really happy with it, a bit like getting a second serving of a favorite meal.
