Turret Opera (A Cappella) - Single

Today, we at A Cappella Records are GLaD to announce a partnership with Aperture Science. To celebrate, a few members of our team invoked the concept of songs solely created by the human voice. And various robotic enhancements. The video involves a cappella music. It is designed to see how test subjects react to a cappella music. Watch the video!
