As far as Emo... Coloring book pages are really meant for children and I doubt companies like Barbie and Matel want to get caught up in that type of scandle any time soon, SO Id suggest some Barbie coloring pages that you can "Emo up" all you want, just use a sharpie to change some of the finer clothing points and use your imagination.

And...well....you said any band, and this Is the best I could find...:

If you'd like to color some band related things, Id suggest you find your favorite band logos then just invert there colors to black and white, gaining a clean slate to color as your feel need be.
Hope this helps, have fun coloring.
