Thanks for the suggestion!
In response to your comments, it is perfectly possible to make a phylogenetic tree. If you know the basic method, you know it's basically down to simple maths - you put the data through an analysis and you get a tree. If you have data, you can do it. A phylogenetic tree is a hypothesis of the relationship - it doesn't say "this is it!" but I'd be interested to see what it would look like.
As for King Crimson being ancestral to Nirvana, this is a claim made by Kurt Cobain himself. Specifically, he cited the KC album Red as a major influence .. just a bit of trivia.
