3rd Dimension is one of the most dynamic Hip Hop groups in America. They hail from Madison, Wisconsin, a place not typically associated with Hip Hop, so they have to be cold. Today, the tight-knit collective dropped their heavily hyped Things Have Changed on the world, along with a music video for “Chosen”. (November 12, 2015). You’re about to get your mind rocked if you’ve never heard of 3rd.
