More than a dozen members deep, A$AP Mob formed in 2006 as a New York hip-hop crew, but their sound and output are borderless: They embrace the waviness of Southern rap, the cutting edge of streetwear, the pulse of electronic music—and collaborators across the musical spectrum. Making stars of MCs like A$AP Rocky, A$AP Ferg, A$AP Nast, and A$AP Twelvyy, the Mob recontextualises the sound of hip-hop's cassette tape undergrounds for the international spotlight, working with Kendrick Lamar, Moby, Nicki Minaj, and Rod Stewart among others
