This is a novel idea: How to mix light rail with music?
The answer is: The Train Tracks, live music on light rail.
The Train Tracks (.org) has been organized to showcase local Phoenix Metro musicians who offer the very best that the Valley of the Sun has to offer. Each week a local band is picked to show a video on the website. Then, the winner each quarter will play to a live audience at the Phoenix Art Museum. A winner from the quarterly events will be selected to play at the McDowell Music Festival.
