Not only did Sulic & Hauser (a.k.a. 2Cellos) cover one of my favorite AC/DC songs but they did the tune all kinds of justice and just when I thought they couldn't make it any better, they went and added Steve Vai to the mix.

I can't put my finger on it, but for some reason I love hearing hard rock and heavy metal on a cello - have ever since I first heard Apocalyptica when they became famous for doing Metallica covers. It's pure genius in that it's one of those things that works really well but is far from obvious.

'Highway to Hell' comes from In2ition, out next year on Sony Music.
