Top Secret Drum Corp is considered to be one of the best drum corps in the world. Their popularity exploded in 2003 with their first invitation to Edinburgh. They have remained top in their field ever since. Top Secret Drum Corp carries a five star rating according to public reviews. People repeatedly state that once they have seen them in action, they do their best to see them every year.
Top Secret Drum Corp shows are highly coveted. They are selective about their performances. They do have a website so people can know when they are coming to an area near them, but one must watch it carefully; once they announce a performance schedule, seats are reserved quickly. They perform as often as possible at the Edinburgh Military Tattoo and did so this year in 2015.
If you are unable to see them live, do yourself a favor and view some of their fascinating performances online.
