Earl Sweatshirt x Frank Ocean – Sunday

Although this year has already seen a lot of potentially classic releases, Earl Sweatshirt's Doris is shaping up to be a one of the music highlights in 2013. After multiple trailers and the Pharrell-powered "Burgundy" single, "Sunday" -- his collaboration with Frank Ocean -- has hit the net. While you might expect a soulful hook on this record, you will find Frank trading verses with Earl over a minimal instrumental, and even making not-so-subliminal reference to his sour relationship with Chris Brown. Doris arrives August 20.
