Which is your favourite metal band? Some would argue it's not metal, but my all time favorite remain Rage Against The Machine. I also like Gojira a lot. I like others too, but I'm really picky and could have strange taste when it's music...
Which is your favourite song? "Esoteric Surgery" from Gojira maybe...
What concert was the best you've gone to? Rage Against The Machine !
Best singer? Hard to tell... Serj Tankian, and impressed by Angela Gossow too (Arch Enemy).
Best guitar/bass/drums/etc. player? I really like Tom Morello unique guitar style and sound.
