The web you see above is only one tiny, Nirvana-centric piece of a cool, new internet toy for music nerds. The Seattle Band Map tracks the connections between the thousands of Northwest-based bands over several decades, from groups with shared members to artists who have collaborated. (A band called The Unnatural Helpers currently owns the title of “Most Connections,” with 43.) Browse the map, search for your favorite artist, and submit any band that’s missing here.
