Sol is your favourite rapper’s favourite rapper because the guy can’t make a bad track on purpose. Though Macklemore put the Seattle scene on the map after gaining some steady traction and then blowing up with “Thrift Shop”, Sol’s been grinding for quite some time, and naturally, he’ll be blowing up real soon. “Jump In” is the audacious cut from Sol (and producers The Zillas) which has that right amount of horns and drums, resulting in a definitive summertime track. The song will be the first single on Sol’s next EP, Eyes Open, that’ll be out on September 10th.
