This is one of the baddest jazz records ever. It's the last time Gillespie and Parker recorded together, and rest of the quintet is the best there is- Roach, Powell, and Mingus. Bird is playing a really mediocre plastic sax called a grafton (he had a habit of pawning his horn for smack, even hours before a gig) but he makes it sing anyway. You also get a sense of what a fucking hipster Diz was back then in some of the chatter between tracks. All in all, a fantastic record.
