Boombox Cartel is back in action after bringing us their insane melodic trap original “Shrapnel” packed with more 808s than any human can possibly handle. Today’s track is their new “WTF Is Festival Trap” remix of Mercer’s “Supreme” and it does not disappoint with the merciless builds followed by the nonstop waves of drilling bass. Top it off with sharp laser bursts are you’ve got yourself one hell of a banger. Grab this one for free off their Facebook page and throw it in your weekend playlist. TURN UP!
