Album: Billie Holiday, Four Classic Albums (Avid)

Pure gold: nearly three hours of classic 1950s Holiday (mostly recorded for Norman Granz on Clef), for about a fiver.

She's been anthologised so comprehensively that it's quite a shock to hear familiar performances in their original sequence. Almost everything here is beyond praise: whatever the setting, the vocal genius is so inescapable that it's hard to focus on anything else. A Latin version of "I Get a Kick Out of You" is worth more than a fiver on its own.
