In April 2015 Young Thug released the mixtape, Barter 6, the fast rising rapper's first solo outing in more than two years. Barter 6 is awash in Thug's distinct style, experimental flow, and innovative melodies, and is highlighted by the anthem, "Constantly Hating" (feat. Birdman). He's joined on additional cuts here by the likes of T.I. & Boosie BadAzz, Young Dolph, Yak Gotti, Duke, and Jacquees while production comes courtesy of frequent creative partners London on da Track and Wheezy.

"Thug has rapidly emerged as the most exciting new voice in hip-hop," declared Rolling Stone. "Thug is at the forefront of a new wave of rappers who don't give a fuck about tradition," noted Complex, adding, "His deliveries are animated and eccentric, bringing idiosyncratic tempo shifts and melodic flourishes to futuristic Southern rap beats." "He has consistently proven himself to be more aware of and interested in probing the sonic possibilities of present-day Atlanta rap than any of his peers," said The Fader, hailing Thug's style as "vivid, brassy and joyful, more melodic than lyrical."
