the funny thing with Sam totman is that hes been playing since he was 8 and is apparantly 'classicly trained'!
I think Herman Li is great though!
The videos on the old DF site had some great 1 take runs through the solos from their first album \ demo.
This video is the funniest guitarist one on youtube imo, apart from the MAB one (now dissappeared) where he gos 'look how ambidextrous i am!' before randomly bashing notes on the twin neck :P
