This is a map of “Louie Louie” cover versions that are currently (as of June 27, 2014) available on Bandcamp. Click on the pushpins to hear each version of “Louie Louie”.
49 versions (so far). Most bands who post their music on Bandcamp add geographic information. I used info this to place each track in its appropriate location. The scale of the map is set to display the entire world but you can use the controls to zoom in to each of the pushpins on the soundmap.
