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.
Guitarist Steve Vai is attempting a world record for "the worlds largest guitar lesson". Interestingly enough instead of getting Vai to promote himself, Spinal Tap guitarist Nigel Tufnel is doing the promo. Check out the promo, plus some classic live Spinal Tap solos next.
