Migos is the latest trio from ATL to take off. "Versace" became a hit when Drake blessed it and since that we've heard remixes from Frank Ocean, Tyga, Meek Mill, Travis Porter and others. If you have somehow missed them (I don't think its really possible?) I really recommend you to check their mixtape "Young Rich Niggas" out. Traplanta is definitely in a building.
