Katy Perry – MTV Unplugged

So often, "pop stars" are palmed off on us with one catchy radio track, and then when it's time to deliver the goods live, we get lip-synching or a middle ear infection from those whose mothers were cruel enough to tell them they can sing. That's you, Avril Lavigne.

Katy Perry is different. Firstly, doing this kind of album is rather gutsy for a pop princess. Secondly, she's got this incredibly malleable voice with an impressive range and power beyond her little frame. She's a treasure to watch, too.

When she introduces the unplugged tracks on the DVD, it's hard to reconcile her endearing, shy demeanour with the same Katy Perry that prances around in leotards and kisses girls.

In this package, she re-imagines five tracks from her One of The Boys debut album, plus a cover and a new track, "Brick by Brick". From the sultry, jazzy sounds of the live band to the personal tidbits, there's so much to enjoy here.

The DVD is more impressive than the CD, though. Not only because Katy is breathtaking in a floaty dress, but because you discover so much more about her. The crucifix on her guitar strap is kind of a 'throw back' to her "faith-based background". She's also not shy to speak about her drug-fuelled journey in her song intros. It's just very sweet and heartwarming. She makes me go "aawww!"

Most interesting track: Her cover of Fountains of Wayne's "Hackensack".

Most memorable quote: "[This song's] about an ex boyfriend who started borrowing my jeans and wearing my own eyeliner. And I believe, in another life, he truly did like the penis."
