This is one of the best documents of Powell's live performances. The sound-quality is acceptable--the only flaw is that while Powell & Roy Haynes are caught well, Mingus's bass is often very obscured (I can barely make out the notes he's playing). The recordings were made in Washington in 1953, & the material is a collection of typical bop chestnuts--"I Want to Be Happy", "Salt Peanuts", "Little Willie Leaps", "Woody n' You". Powell is in amazingly sharp form--none of the stumbles & vaguenesses of his later, lesser work: he's got a decent piano & gives it a very crisp attack. One of hte pleasures here is that while most of the tunes are dispatched in 3-4 minutes, a few of them considerably stretch beyond the length of your typical bop single, notably a 9-minute version of "Salt Peanuts".
There is a 5-minute interview at the end, conducted in 1963 in two parts, in France. This was recorded while Powell was recovering from tubreculosis in a sanatorium; on the first he sounds extremely haggard & spaced-out, on the second rather better. Though they don't contain any extraordinary insights they're rather moving to hear.
Great stuff for bop aficionados; casual listeners will probably want something in better sound unless they're used to listening to airshot material & the like. Ignore the supremely tasteless cover art (it shows Bud Powell's head distorted into a picture of madness, Francis-Bacon-style), & check it out.
