4. Young Thug & Bloody Jay, 'Black Portland' and Rich Gang, 'Tha Tour Pt. 1'
Atlanta's Young Thug started 2014 on the fringes of rap, having accumulated a small following by reimagining Lil Wayne's career as never leaving the place where he felt like dying. Young Thug ended 2014 more integral to Cash Money Records than Wayne himself. This evolution from avant curio to reliable radio hitmaker can be traced in the distance between Black Portland and Tha Tour Part I, the two mixtapes that bookended his year. The first, with fellow ATLien Bloody Jay, oozes with mumbled hooks and verses so esoteric that it sometimes feels like the two are interpreting each other's hieroglyphics. The second, with fellow radio staple Rich Homie Quan, features a half-dozen songs that could — should — be getting airplay right now. Black Portland starts with a lullaby about fellatio; Tha Tour with a regal, clear-eyed ode to a luxury clothing brand. Black Portland peaks with a song about staying true to your homies; Tha Tour with a celebration of living life like Flavor Flav. Birdman, currently the most powerful mogul in rap, shows up on only one of them — it's the one that ends with a song called "Who's On Top." J.S.
