Our updated site, hope you dig it.
Multisite install allows bands to create accounts / manage blogs, some custom plugins I wrote allow managing music, and I hope to integrate album sales in the near future.
Don't think we would have gotten it as far as it is currently without WordPress. Still lots of little things to tweak, fix, expand, etc., but thought it was far enough along that it was worth sharing.
Thanks for looking and appreciate any feedback.
