Crystal Lake Thunder is the Independent A Class affiliate program of The Cavaliers presented by Crystal Lake Strikers of Crystal Lake, Ill. This second-year percussion ensemble offers young male and female percussionists a competitive performance outlet in the Chicagoland area that builds on the shared resources, style, and excellence of The Cavaliers' award-winning programs and ensembles.

Thunder is a co-ed percussion ensemble that competes in Winter Guard International’s Independent A class, with The Cavaliers providing direct assistance in the areas of staffing, instruction, design, and operations. 

“Teaming with the Strikers to create Crystal Lake Thunder as an affiliate is an exciting step forward for our growing family of Cavalier programs, including The Cavaliers Drum & Bugle Corps, Cavaliers Indoor Percussion, Chromium Winds, Classic Cavaliers, and GearWORKS,” said Chris Lugo, Executive Director of The Cavaliers' organization.

“Dramatically increasing the number of students we serve is a key priority for us, and I’m glad that we’ve found a great opportunity to partner and deliver a new competitive performance experience for local students with the launch of Thunder!”
