Corey Taylor from Slipknot.
Everything he does interests me, he's cool, he's funny, he's down to earth, he's closed to his fanbase, and he's involved in a lot of projects that makes him more than a heavy metal band's lead vocalist.
He's even sexy in some way
I also really like Muse (the band). Everytime they get something out, I'll definitely listen to the whole thing. They have many different styles, from hard rock to classic/opera, to epic ballads and sing-along songs.
Oh ! And they totally R-O-C-K live !
For all electro listeners, Daft Punk is most definitely a classic. I'm personnally not a huge electro fan, but I'd miss a Daft Punk gig for nothing. I've seen them in 2007 at the Bell Center and it was one of the best shows I went too. A phenomenal experience !
So yeah, definitely those three... And a bunch more !
Oooooh ! I almost forgot ! My little touch from Montreal. Patrick Watson (it's the lead-singer's name, but also the band's name) really deserve to be known all over the world. Is music is genious !
