Album: Amy Winehouse, Amy Winehouse at the BBC (Island/Lioness

While there's a limit to how many times one can watch old clips from Later… or the sublime-to-ridiculous Porchester Hall show, you can't deny the power of this three-DVD-plus-one-CD collection.

Winehouse's progression from fresh-faced ingénue to agonised diva is operatic stuff. The CD includes a fantastic slow version of "Valerie" and two straight jazz numbers with John Dankworth in the band. Oh what we have lost.
