Last night at the Alternative Press Awards we were treated to something special: Babymetal and Rob Halford on stage together performing Judas Priest’s “Painkiller” and “Breaking The Law.” There’s nothing quite like watching Halford perform with another singer with a high-pitched voice; it’s like they’re having a HYEEEEAAAAHHHH-off and whoever bursts the most ear drums wins.

It’s definitely a little weird seeing “Painkiller” come out of instruments played by Babymetal’s Kami Band instead of from the dudes in Judas Priest wearing half the world’s supply of leather. I will say, however that over the course of the years the opening drum line to “Painkiller” always puts a smile on my face no matter where I hear it. Even if it’s played terribly — and it definitely isn’t here, the performance was great — it still makes me happy to know that somewhere in this world someone is playing an instrument because of a bunch of guys wearing leather pants. But I suppose that’s all of rock n’ roll, really.

You can watch the performance for yourself below. Don’t turn the volume up too high or you’re going to shatter every window around you.
