Daytrotter. This site offers free downloads of live recording sessions of so many bands and artists. It's a great way to discover new music or to simply find live recordings of some of your favorite artists.
The Daytrotter studio is unique, in that it is located in Rock Island, IL. This small midwestern town is basically in the middle of nothing, much less a thriving music scene of its own. But because of its location near the highway and Mississippi, many bands traveling through the area will make a stop at this small town simply for the sake of connecting and recording with Daytrotter.
There is actually an documentary in the works, called Welcome to Daytrotter, about their story and what has happened since their start in 2006. I recommend checking out their site.
And here is the trailer for the film:
