These teens from the O'Keefe Music Foundation have two things going for them – a sense of humor and a killer musical ability. The kids take on Slayer's "Raining Blood" and nail it in every single aspect, though it's also worth noting that the music video is well-shot and pretty funny.
Don't be fooled by the first 50 seconds either. The acoustic performance has nothing to do with the actual song, and the acoustic guitar is promptly and quite literally thrown by the wayside.
We've covered the (different) kids from the O'Keefe Music Foundation before, as they've covered Tool, Slipknot, and Danzig in the past.
