Now if you want to hear a really "loose" Blakey, check out "Nihon Bashi" on Kyoto. WHOA!
And hey, no discussion of great Blakey performances, trumpet-centric or not, is complete w/o a serious consideration of the 5/13/61 Olympia gig released on RTE/Trema/etc. That's "HOLY SHIT!" material if ever there was any.
