Blue Knights Drum and Bugle Corps from
Denver, CO. World class DCI, consistently a finalist corps.
BK is known for their weird ass shows, like that one about
Egypt, and the ones that make you cry.
On their corps necklaces, they wear Enzos, which are washers with custom designs on them. Each year, the Enzo design is a representation of the show from that year and is a token of all the memories from that season.
