In celebration and promotion of his new project, Plug Research's Thavius Beck compiled some unreleased material and mixed it to create a nice 15-track mixtape. Thanks to Beck and the ever-generous folks at PR, the tape is available on their website to the listening masses for the small nominal fee of one's email address. There's no greater joy than indulging in generous helpings of free music. Check out the tracks below and head over to PR's website where you can stream and download the entire mixtape. Also, check out Beck's recently released EP The Heavens Bleed Sunshine, available now on iTunes.
