This is certainly no ordinary drum corps. The Top Secret Drum Corps not only an interesting style, but an intriguing history as well. Founded in 1991 in Basel, Switzerland, the Top Secret Drum Corps features 25 drummers and color-guard members who play and move in complete precision. Because practice is highly demanding, and often every day, these 25 members are constantly changing. They range from college students to factory workers, with every profession in between. The traditional drumming society in Basel, a town said to have over 3,000 active drummers, initially disapproved of Top Secret's style. However, as the Corps has evolved over the years and experienced great success, much of that disapproval has faded away.
