Chance the Rapper, 'Acid Rap'
On his wildly anticipated second mixtape, Chicagoan Chance the Rapper at first sounds a bit like Lil Wayne or Eminem. But his vibe is more Kendrick Lamar and Kanye West, his voice shifting between fleet rapping and rap-singing. His beats have a woozy, psychedelic feel. Don't be surprised if someday he's spoken of in the same class as his influences.
From the RS review: "The density of wit, ideas and verbal invention that makes this one of the year's defining hip-hop releases."
