If you don't live in this area, you may not realize that while Detroit proper is a wasteland (and Detroit proper is very large), the metropolitan Detroit area is doing OK. Not great, but OK, and it has a lot of other stuff in it. In most of the Metropolitan area, you'd never even know that the theoretical flagship city has been destroyed. There's still a big market for national acts to come here and draw from the rest of the metropolitan area, the Lansing area, Ann Arbor, and so on. For concerts, Toledo residents can reach, too.
