Weddingbee boards

We are looking for musicians for our wedding and having a tough time. We really don't want the traditional stuff. We really love Andy Mckee. We also love bands like This Will Destroy You and God Is An Astronaut. Unfortunately, these bands are pretty huge now, and I am sure are uninterested in playing at our wedding ceremony. Does anyone know of similar artists who haven't exploded that would be interested in playing at our wedding? Those from the midwest would be the most practical.

Thanks!
