It’s hard to believe but some musicians out there are in more bands than Jack White. BandToBand.com has created a unique web site to “map the Rock and Roll Genome.” It’s like the Six Degrees of Kevin Bacon, but with Slash and Dave Grohl.

Bands have a tendency to share band members from time to time and as a result it is not difficult to construct a simple "family tree" based upon the interrelationship of band members. We at BandToBand.com decided to find out how large this extended tree is. Every band in our list is connected to every other band based upon this family tree principle.
