Earl Sweatshirt paints his pain. On his new album, the Los Angeles MC masterfully unveils his struggle with depression, addiction and anxiety; a cocktail of emotions that he vomits out in his introspective raps. These same issues led him to cancel a tour and take a three-year hiatus from music. On top of all of that, his dad died last January. A 15-song, 25-minute album, “Some Rap Songs” breaks Sweatshirt’s musical silence.
