I saw them in early 2000 as they were the opening band for Foo Fighters and Red Hot Chili Peppers in the US. They were incredible, just a wall of sound and that wailing operatic voice. I got their CD and it never really grabbed me the same was as their live stuff. And the later singles I heard didn't do much for me. But that show the same time you saw them was awesome, especially in a big arena.
I saw the show in a tiny club with barely 1000 people there it was insane! Matt Bellamy is a madman on stage haha.
