The Blue Diamonds Drum & Bugle Corps is a nonprofit and recognized as a particularly eligible youth organization, which deals with the practice and promotion of modern brass music. Following the American model, music and shows are combined in performances and competitions. A combination of sports and music probably explains this special style of music best.

The Blue Diamonds are a well-known and popular youth organization in Nienhagen and the entire region, where playing an instrument can be learned as well as taking on responsibility in a large community.

For nearly 35 years, the Blue Diamonds have been participating in parades, festivals and competitions throughout Europe as one of the few German Drum & Bugle Corps. Performances in Spain, Italy, France, Poland, Italy, Denmark and the Netherlands have already achieved considerable success. Regular participations in the German, European and World Championships are just as much a part of the action as appearances at the Chancellor, on radio and television appearances up to the Formula 1 Grand Prix in Monza or parade of the pilots in the 24 Hours of Le Mans.

Everywhere the Corps proved to be an outstanding ambassador of the region or of Germany.
