Last week, the Philly hip-hop duo Moosh & Twist released their excellent new mixtape Back To The Basement that you can download here. To go along with it, there’s a new video for one of the new songs, the anthemic “Top Of The World.” The video was filmed with a classroom of adorable elementary school kids at the Philadelphia School (at 25th and Lombard in Center City, Philadelphia), which is where Moosh & Twist met in 1st grade. Watch the video below, and go here for a close behind-the-scenes look at the day Moosh & Twist went back to their former school.
