Artist: Various Artists
Album: Kick Out the Jammies
Description: The 11-song sampler from Burniside Distribution is the second free Amazon sampler (here's the first from a couple years ago) from the Pacific Northwest distributor, and it's a solid collection, with great tracks from Key Wilde & Mr. Clarke, the Verve Pipe, Recess Monkey, Caspar Babypants, Cat Doorman, Readeez, and more. In fact, you should probably have a lot of those tracks already, so get it for the ones you don't know (or your less-savvy friends who refuse to take your sonic advice).
