There is the Blockhead that has been a fixture of the electronic music scene for more than since his 2004 Ninja Tune debut Music By Cavelight; putting out a string of critically acclaimed albums and touring with everyone from Diplo to Amon Tobin and Kid Koala. Then there is the rap producer Blockhead, whose collaborations with Aesop Rock-Labor Days, None Shall Pass - are part of indie hip-hop canon. The veteran who collaborated with luminaries like Cage, Illogic and Blueprint but also made memorable records with then little-known artists like Despot and billy woods early in their careers. Free Sweatpants is the first time the two Blockhead's connect, in what is really the most appropriate form. A mixtape-esque album that pairs his narrative-driven solo aesthetic with a team of rappers that thrive in Blockhead's layered, melodic sound. Aesop Rock, Tree, Breezly Brewin, Open Mike Eagle, Homeboy Sandman, Armand Hammer, Vic Spencer, Hemlock Ernst, MarQ Spekt, and billy woods round out the guest list.
