An interesting mathematical equation appears in today's Washington Post. The mathematical equation is about the extent to which an artist is a sellout for allowing a song to be used in commercial advertising for a product (and be compensated for doing so).
The article uses Led Zeppelin's "Rock and Roll" on Cadillac commercials as one of several examples. And it turns out that, once the equation is applied, Led Zeppelin's sellout isn't the world's biggest! Good to know.

I'm down at the National Folk Festival in Richmond, Va., today. Mike Seeger (see previous post on his involvement on Raising Sand) is down here, and I'm hoping to say hello in person.
