fun music-related scavenger hunt

Hey guys. Every winter I do a research contest that involves figuring out where random pics are from. The theme of the contest this year is music, so this should be easy. :) However, these are the leftovers from over 70 that my team has yet to identify. So, they are the toughest ones of the bunch.

The pics are here: http://mysterytown.weebly.com/

Please use the form linked on the page if you have any hints.* ANY information is valuable, even the faintest idea of a recollection will help us. They may not be music related, but clearly there are some band photos.

Thanks a ton, everyone! :) Let me know if you have any questions.

*We use the form because other teams are looking for the same pics, so we obviously don't want to help them!
