Better Late To The Party Than Absent: Canon Rocks!
Oh. My. God. I can't believe I never watched or heard this before now. (Well, that's probably because I'm not a YouTube addict, and can I just say I think that's a good thing? I have enough timesucks in my life...). I have a very special fondness in my heart for the good ol' Canon in D, and hearing it done like a thrashing metal guitar god solo....it makes me so, so happy. This one is going right on the "Undercover" mix I've been making of various cover songs (and no, Josh, I don't care whether this is technically a "standard" and not a cover--to me, any unfamiliar/unexpected version of a familiar song is a cover). Squeeeeeeal!
I'm sure you can be resourceful enough to get your own downloadable mp3 if you like. Even I managed to do it.

Holy crap. While the entirity of that rocks, I'm seriously far more impressed with his manual dexeterity. That was literally like a 5 minute solo. My fingers hurt just watching.
