Previously unknown Diz/Bird concert discovered!

At the Town Hall concert, the musicians were free to play the tunes - "Bebop," "Groovin' High," "Hot House," "A Night in Tunisia" and "Salt Peanuts," all jazz anthems by the end of that year but at the time still unknown - for twice as long, and at a furious tempo. Solos went on for two minutes or more, and they're blazing - Diz scaling heights on trumpet, Bird hitting speeds on alto sax, that no one had heard before. The studio recordings, great as they are, sound mellow, even quaint, by comparison.

Man, I'll take one of those!
