They share an Alma Mater. Perhaps this collaboration was discussed at a reunion.
My job just got extremely easy. This is a split 12″ by Burial and Four Tet. The artwork is all black, the 12″ is presumably sold out and information regarding this release is virtually obsolete. Also, I have no clue as whether any further collaborations are in the works.
I do, however, have it here for your listening pleasure.
