As an A$AP Mob affiliate, Marty Baller has no problem getting connected. After dropping “Big Timers” with A$AP Ferg and “Roll the Bud Up” with Smoke DZA, he has recruited Ferg once again and now Migos for “I’m A Dog.” Produced by lordxprynce, it’s just what one would expect from such a collaboration—a banger. Baller’s debut mixtape, MartyGraW, is scheduled for release on Friday (November 11).
