Ok, I hope this in the right place.

I'm doing A-Level music, and I gotta play 8 mins of music, from 3 pieces. Preferably the pieces are whole, and of a reasonable difficulty. I've got one, and this is about the hardest sort of stuff I can play (It's the last ascending lick in the solo that gets me, the rest is fine!): Crazy Train, By Ozzy

Any suggestions? Any style is fine, and I'll be grateful for anything.
paranoid by sabbath, not difficult but really ass-kicking
Höhner llx100g
Gibson explorer
crappy stagg acoustic
Roland dac80d
marshall jcm 900 sl-x 2500
marshall 1960A
ehx metal-muff
jimmy hendrix wah
Sabbath, not a bad Idea

And ok, they love classical stuff too

Thanks guys, I'll give 'em both a shot and see what they think
