An ingenious idea, Podbop allows users to browse a list of recordings by bands playing shows in your area. Recent additions to the site for New York City include tracks from Alkaline Trio, Orthrelm, Darkest Hour, NOFX, Metric, Black Rebel Motorcycle Club and many many more.
The idea is to allow concertgoers, who increasingly face high ticket prices and a bewildering array of options (in major cities at least) a means of deciding whether they really like the bands associated with cult label The Social Registry or if a show by James Blunt is really more their cup of tea. A nice service utilizing one of the most interesting new channels of communication out there.
