I love free album downloads, and not just because they're free. I just like getting free samples of music I might not otherwise listen to. Case in point: Liberation, the new collaboration between Talib Kweli and Madlib. Right now, the duo is offering the album as a free download online; you get a Zip file and import the songs into your iTunes or other software. I'm really digging the mellow vibe, and the album has the lyrical acrobatics I've come to expect from Madlib. Give it a listen and tell me what you think.
