A lost track from Earl Sweatshirt suddenly appeared out of nowhere today. "Rats," produced by Tyler, The Creator, is Sweatshirt is usual form of unapologetic and rambunctious rhymes over hard drums. Last week, Earl canceled the remainder of his tour dates in England, Belgium, Canada, Germany, Switzerland and Chicago because of illness. But, he did announce that he'll be finishing up the follow-up to his debut album Doris, which was released last year. Check out "Rats" here.
