I hate when bloggers brag, but I love Pigeons and Planes…just saying. Here is the final version of The Alchemist track featuring the Gym Class Heroes frontman and Weezy. An earlier version leaked but Alchemist decided to redo it and releak it himself. This beat is serious. I wasn’t sure if this trio would work well together (autotuned Wayne over an Alchemist beat?), but welcome to 2009. Chemical Warfare is out tomorrow (7/7). Credit to NR.
