This is a classic pub discussion, one which I thought I'd put on LJ. I encourage you all to play. Basically, put together a band with your favourite players, whether from various bands or soloists. Only one member from each band, though. It's no fun to just say John, Paul, George & Ringo.
Guitar/Vocals: Alexi Laiho (Children of Bodom). One of the best guitarists going right now, but he's in mostly for his ability to know a tune. Would handle the harsh vocals.

http://uk.youtube.com/watch?v=8gw4NDVQn2I Bass: Ted Lundström (Amon Amarth). Very heavy bass. Shook his hand in Glasgow!
