An annual indie hip-hop festival that gets bigger every year, A3C (short for All 3 Coasts) brings the underground's brightest stars and most promising newcomers together for a weekend full of performances and events in Atlanta. Though they've assembled small-run mixtapes in the past, this massive compilation is their deepest and most diverse to date. Loaded with a whopping 45 tracks, Vol. 1 showcases much-loved and well-established acts from around the country, including 9th Wonder and Big Pooh from the late great Little Brother, New York favorites M.O.P., Saigon, Dead Prez, Smoke DZA, Golden State representative Murs, and Massachusetts monsters Statik Selektah and Termanology. Buzzworthy rookies Freddie Gibbs and Action Bronson strut their stuff, as do impressive unknowns like Phil Ade and XV. Production styles run the gamut from skittering Southern anthems to moody, sample-fueled boom-bap; there's really something here for everybody. Billed as an updated version of the legendary Soundbombing collection, this is a great mix perfect for hip-hop heads.
