Concentrating ten tracks into 24 minutes admittedly sounds like a recipe for empty brevity on paper. However, rap fans already know about Thebe Kgositsile (Earl Sweatshirt) and his demonstrated power of shorter songs from his critically-acclaimed masterwork Some Rap Songs. Released early this year, SICK! follows the Chicago rapper’s trajectory of reduced album lengths, yet it plays like his most musically expansive. Assertive but atmospheric production buoys each track with a mix of nostalgic references and modern synth flourishes, and Kgositsile’s lyrics on the whole album are more contemplative than ever before.
