Astronautalis and Doomtree's P.O.S. have joined forces to create Four Fists. The collaborative duo have released a new song entitled "MMMMMHMMMMM" from their forthcoming 7-inch which will be released in four different colors (blue, white, red, clear) via Doomtree October 8, 2013.

Two special pre-order packages are now available here; both of which include a copy of the 7-inch signed by P.O.S. and Astronautalis.
