I know this is going to sound funny... but the new album from Gangstagrass is hot to death! Seriously... A mashup of bluegrass with hip-hop... It has a comfortable feeling, almost as if you've heard it before. The production value is through the roof, for a free album...
Whao... Wait? Did I say FREE album? Yup! Go snag the torrent while you're bored... and go check them out! If you know me, you know how much music I listen to and how diverse it is... this is something I recommend...
