1. Rage Against the Machine
2. Slipknot
3. Marilyn Manson
4. George Clinton / Parilement Fundadelic
5. Deftones
I don't like Slipknot's music much, but they are insane live. I nearly passed out in the pit, they really get the fans going.
Marilyn Manson sounds good and puts on a good show too.
Seeing Rage Against the Machine in June which I'm really looking forward too.
I didn't think much of Deftones live though, even though they are one of my favourite bands.
But hey, like you said, it's all opinion.
