Infinite Degrees of Separation

Ever wish you could hold forth on the connections between bands like Jack Black and John Cusack in Hi Fidelity?

Well, I do anyway.

BandToBand.com : Hot Rockin! is amazing. Click any two artists, and the system shows you the degrees of separation between the bands.

Seriously. I tried the Eagles and Black Flag, and it found a connection.

On the one hand, it's very cool.

On the other, there seem to be a few albums that everyone in the world played on.

Worth a further look.

Yes, I'm crushingly busy today.
