There is, sadly, not much of a busking scene around Phoenix's new-ish light-rail system. Sure, you might catch a rogue saxophonist blaring out "Baker Street" on a metro platform from time to time, but not often. No, the real music/light rail mash-up comes from The Train Tracks, a bi-weekly series. (New Times has a loose association with The Train Tracks, now helping pick acts who play; but even before that, we thought it was super-cool.) The gist: Local bands hop on board and play their best songs while the riders around them watch in awe, bemusement, anger, or indifference. The "what's gonna happen next" factor always gets us excited, especially if there's a cranky old man nearby. The Train Tracks is all about our city's best bands utilizing our city's most ambitious public works project in a generation, and that makes it well worth tuning in every two weeks.
