Oh this is a pleasant suprise. I am in the Dutch Military Academy Tambour Corps, which isn't much more than a Drummer band.
We do occasional performances at civilian festivals (local only) and some national stuff, such as the 'Avondvierdaagse', where we do musical backing of the hikers
At the academy itself we do the obvious military marching music, accompanying anything from platoon to battalion to regiment sise (entire academy). Unfortunately we do not practice much drill so sometimes the quality leaves a little to be desired and especially because of the way the Academy is organised, we get new people once every half year.
