The free app shows users a map with stars' birthplaces, historic music venues, album cover sites, festivals, recording studios and more rock-fueled landmarks.

Users may contribute to the database by letting the app know of any missing music landmarks. So, if you went to school with a future rock star, know a local location of an album cover photo or attended a historic gig at a certain spot, you may send your own landmarks and photos to be included in the app, which will be updated every month.
