The Top Secret Drum Corps is a precision drum crew based out of Basel, Switzerland. Though many talented drum corps exist around the world, the Top Secret Drum Corps set themselves apart from the crowd as they are not associated with any military. In fact, most of the corps' membership is comprised of college students and people with normal day jobs. It's through each member’s dedication that they have become one of the first non-military and non-British Commonwealth acts to take the stage at Edinburgh Castle, Scotland in 2003.
Made famous by their 2003 success, the group has been re-invited to perform at Edinburgh on multiple occasions. In their 2012 performance, they definitely pulled out all the stops to put on this breathtaking performance.
