The top 3 Google results for "Brazilian Funk" are the Wikipedia article, an NPR story, and a compilation CD from CD Universe.<p>Seems like the least you could do to put up a quick primer on the genre (it will be slicker than wpedia), swap links with prominent bands (better rankings), and maybe put up some announcements and a forum.  You could focus the information on making it easier to transition from curious to interested to fandom.<p>The big questions are how much the musicians would be able to support a site like that, and how willing they'd be to coordinate with each other.
