Lyrical Shoutout: N/A

Who they are and what they do: A$AP Yams was famous even before he stepped out from behind the computer screen, and way before he got the New York Times' treatment. An early-ish presence on Tumblr, Yams ran the influential Real Nigga Tumblr blog, a concoction of UpNorthTrips, noz, and Harlem bodega-vision. But that's ancient history from 2010.

Yams is best known as the mastermind behind A$AP Worldwide, an incredibly savvy svengali in the tradition of an Irv Gotti or a Puffy. He approves instrumentals, he's responsible for throwing A$AP in front of everyone's names (a la Bone Thugs). Manager, friend, A&R, he is the center. Boundlessly hilarious, he's great for a quote—"the Puerto Rican R. Kelly"—also can be found lamping and bopping with the bottle heavy, everywhere from "Purple Swag" and "Goldie" to A$AP Ferg's "Shabba."
