Re: Zach Hill!!!
He's definitely one of my top favorites, and one whom I'm currently listening to for inspiration, via "Hold Your Horse Is" album. Very technically complex, powerful, and energetic.
I highly recommend Hella's live DVD "Concentration Face". It's got great live footage, and a lot of it. A good insight into Zach's amazing playing style and technique. And he has some tremendous endurance; the 2nd part of the DVD is a gig consisting of their fast, complex music lasting over an hour.
