Video: DubbleOO Space Age - "Speed of Sound"

2012 continues to shape up as a strong year for DubbleOO Space Age, the rapper who splits his time between the Bay Area and his native Portland. He has two albums forthcoming, an official sophmore solo effort as well as a joint album with Bay figurehead The Jacka, but first, DubbleOO continues to build towards the online release of his latest mixtape, Beast Mode, Vol. 2. Today, DubbleOO is excited to release that tape's latest visual, for the song "Speed Of Sound."
