Bonnaroo

site needs to be more exciting, there is too much white!

Sasquatch

great colors, love how they play with color in the header

Coachella

love black background, artsy feel, sketch-like appearance

Acl Festival

love black background, if only i knew how to use flash - music notes coming from birds mouth in banner, grass moving at bottom of main div

Linkin Park

not a huge fan of the layout, but noticed something different I haven't seen on other sites. Round quick links in right-hand corner. You normally see them as square shapes. Background image seems to busy and doesn't really go with the bands genre.
