I actually really, really put some thought into this one, and came up with about 15 bands that I could see playing a festival and their sounds would compliment each other while being broad enough to see a decent amount of diversity in the fans. Goth, punk, rock, funk, hip-hop and industrial all have big support here, as do each of the bands having a lot of stage presence. Bands that I really, really, really wanted to put in here and just couldn't keep one of the bands below off: Strapping Young Lad, The Dead Weather, Immortal Technique, Napalm Death, Deftones, Rasputina. But i just feel like the groups below would all compliment each other and their styles and sounds the best.
