I don't have more information than the link (and no personal experience), but just today I saw an announcement about FairCamp, a free (open-source? not sure about that part) static site generator for audio producers. I always worry about third-party hosting services going poof and taking my stuff with them, and since you're self-hosting anyway, maybe you want direct control? No idea what the tradeoffs are, what the risks and costs are with BandCamp, where the hassles would be with self-hosting... but I can forward a link, at least. :-)
