About The Crystal Lake Thunder

Crystal Lake Thunder

The Crystal Lake Thunder is a competitive indoor drumline, created as a collaboration between The Cavaliers Drum and Bugle Corps of Rosemont, IL and the Crystal Lake Strikers. The Cavaliers had a competitive group named "Green Thunder", which over time became known as "Cavaliers Indoor Percussion". Crystal Lake Thunder is a rebirth of Green Thunder, with an emphasis on fun and challenging percussion performances, expanded to both young men and young women students.

Indoor drumline is a competitive winter-based pageantry art centered around rudimental marching percussion. Stemming from competitive marching band, as well as drum and bugle corps, the indoor drumline activity encompasses scholastic and independent circuits under one umbrella organization called Winter Guard International - or WGI. Thunder operates as an independent group, competing in the Percussion Independent A class. Most students of independent organizations range in age from 14 to 22, at which point you graduate from the activity. Each ensemble prepares a floor show lasting under ten minutes, and spends their season rehearsing and perfecting their program until meeting in Dayton, Ohio for the WGI Percussion Championships.

Why join Thunder?

First off, it is fun!
Students that commit to an experience with Thunder are promised a top-caliber education in the realm of marching percussion. Beyond receiving instruction from a cohesive staff with decades of combined drumline experience, students will develop excellent habits - not only in the artistic realm of musicality and performance, but also the disciplines of personal accountability, time management, rehearsal etiquette, and teamwork. In the end, the most valuable aspects to gain are the lasting friendships and memories earned through a season of togetherness and perseverance.
Thunder is an affiliate of The Cavaliers, and will give each member a "Cavalier Experience", which means challenging the member to be their very best inside a supportive structure.

How much does it cost?

The precise budget is still under development, however, tuition is estimated at $1000 for the season. As we understand that students and families are met with varying financial situations, we will have payment plans to address their needs.

How often do we practice?

Rehearsals are generally each Saturday from 10a-9pm at Strikers Hall 100 S. Main Crystal Lake IL. As members move through the audition process, they will be asked to fill in a commitment sheet with their availability for the season.


Overall, the season goes from approximately December through April. School conflicts must be cleared in advance. Click here for the Google Calendar for Thunder.

How can parents help?

Parents are absolutely vital to the success of the group. While nothing is formally required, the organization typically asks for help from parents with driving equipment trucks to venues, sewing uniforms, organizing potluck dinners, and varying other logistically-oriented positions. If parents have any special skills (such as building props, transportation, fundraising etc.) and are willing to lend their abilities, please notify us of your specialties.
