As others have duly noted, Facebook has added a feature for musicians' promotion, and I have jumped in with a new Facebook page of my very own. I agree with Darcy's assessment- the look is pretty generic, and the navigation and editing features are pretty clunky. (though on the plus side once I got past the "CID" part of the process, putting music up was easy and painless.) It seems ridiculous that a site that is so clever in friend mode- you can throw sheep, for heaven's sake- is so dull here.
That said, I make do, and would appreciate your fandom on the new page. As with everything else in my life, it's a work in progress, and will hold me over promotionally until I can put Patdonaher.com up. And just to make it worth your while, there are two never-released sound clips on the Facebook page. One is a promo version of the No Sale Value tune "Jackson", and a live duo with the amazing Bob Brookmeyer. For a limited time only, so check it.
