Saw them with Cradle of Filth last night. Cradle were good, but holy shit, Behemoth were a whole different level! Quite honestly I'd say they were one of the best live bands I've ever seen, and I only really know a couple of their tunes. Machine like levels of tightness, great tones (especially Nergal's lead sound), great stage presence and one hell of a show, plus the songs they chose were just a mission to tear the world a new arsehole.
If you've not seen them, you owe it to yourself to go and see them.
Behemoth are often underrated as musicians.
Some of their tracks and albums are hit and miss, but when they're good they're fucking incredible. Not seen them live, unfortunately.

PS: The above track, with the rest of Evangelion, is 6 tracked: 3 per side. 'Machine tightness' is about right.
