fucking easy question, the Rock one, tho I like many music genres rap and hip-hop are meh...except for Cypress Hill and Outkast, shit would love to see those guys but they never seem to come to Europe
BTW Linkin Park live (and without beeing live also but thats another story) sucks.
Bands like Defontes, SOAD, Static-X, among many others are so much much better
