love this, and the other poster to go with it (distillers). i understand it might not reflect exactly all the band styles (i only really know of melt banana) but the artwork is so cool, you're going to look at it no matter what. besides i think the circus/sideshow theme almost uaually works if you have a variety of music (or maybe i'm just a fan of the theme!)
I know that you have a problem with artists that don't fit band imagery to the posters. I am always trying to come up with something that the band will like that will become part of their imagery, not something that has been done for them before.
I'll let you know how they liked it.
