Oy vey, there are waaaaaay too many music marketing blogs out there these days...  Which makes having found one that simultaneously inspires, confuses, and awes a rare event.  If you have a chunk of time on your hands, definitely read Audible Hype's post on high concept, low cost, brilliant multi-level media campaigns. Here is one statement of absolute truth:

It's long, but worth the read.
