The guitar skills needed to cover a Slayer song like "War Ensemble" are pretty significant to say the least. That's why this particular rendition by a -- wait for it, wait for it -- 10-year-old girl named Audrey is all the more impressive.

Don't be misled by the gaming system -- this is not Guitar Hero, Rockband or similar, simple button-pushing video games, but Rocksmith, a system that uses real guitars in order to teach and hone actual skills at playing.
