Black Veil Brides shouldn't be considered an Ohio band considering they were called White Wedding at the time, and didn't adopt the BVB name until Andy flew to LA and recorded the later demos and We Stitch These Wounds.
I know it's been an entire year since anyone posted here, but I really liked this list. Shows that there's a lot of good music from my home state... But also some really, really bad music (I'm from Columbus, btw).
I would also add Lo-Pan, The Afghan Whigs, House of Heroes and The Sidekicks as well.
