The Naughty Little Purple Imp, sadly, never released any of his golden albums in glorious surround. But barring a few live numbers on Purple Rain, the concert film of Sign 'O The Times in Dolby Atmos is about as close as you can get. The only addition is a little snippet of Little Red Corvette, otherwise it's pretty much the whole album - barring Starfish and Coffee and The Ballad Of Dorothy Parker. This should have been included on the humongous re-release of the album last year. You can listen without watching the movie, or thrill to the spectacle of Cat Glover gyrating like a banshee throughout.
