Musical Family Trees...

A thread on what artists you have the most of in your collection just got me thinkin' about how I file successor bands under the original band in my alpha collection--people think I'm strange, b/c the Throwing Muses shows up under the Pixies. Frankly, a *lot* of stuff shows up under the Pixies.

Anyway, I remember a book from the 70s or 80s where someone graphically laid out the family tree of a number of different bands--who played with who, incarnations of acts at different times, stuff like that (anyone remember the book? I'd like to try and find one, but can't remember the name of it). There were some surprising results in terms of who is related to who indirectly . Seems like this is the kind of thing an internet database would be great for. Anyone know if anyone has done anything like this?
