Some Peter Green fans might be put off by this 64-song/four-CD collection, owing to the fact that they are likely to already own a significant chunk of what's here (especially the Fleetwood Mac material). (And in fairness, there apparently isn't a lot of – or any – unreleased material to draw on from Green's classic period with the band). But this reviewer had to spring for this four-and-a-half hour showcase of his work, and for one major reason – vitality. Green's virtuosity is a given, and his taste and his insights into blues and what can be done with it – while still leaving it as blues – are well known to anyone who's heard his work.
