8. Earl Sweatshirt
After Earl Sweatshirt gained as much attention for his absence from rap collective Odd Future as for his highly acclaimed 2010 debut Earl, the teenage MC reappeared last year after finishing high school in Somoa. In addition to rejoining Odd Future and contributing to Frank Ocean's Channel Orange in 2012, the rapper is working on the major-label follow-up to Earl, tentatively called Doris. He previewed the album last December with a video for the single "Chum."
