2021 brought drum corps performances back to stadiums across the country, and featured many exceptional moments in what ended up being a special — albeit unconventional — year for the drum corps activity.

Take a walk down memory lane and relive the top dozen moments from 2021 as seen on DCI's YouTube channel:

11. • U.S. Marine Drum & Bugle Corps | 2021 | DCI Celebration Indianapolis

6. • Father Son Drum Duo

One of the highlights of the DCI Celebration at Lucas Oil Stadium was the many solo and ensemble performances presented on the GPG Music Stage, including a snare drum duet performed by longtime DCI percussion judge Jeff Prosperie and his son Jeff Prosperie Jr., a member of the 2021 Phantom Regiment.

3. • 2021 Phantom Regiment – "Elsa's Procession to the Cathedral" Encore

Phantom Regiment joined the many corps who presented compelling encore music at the DCI Celebration, performing Richard Wagner's "Elsa's Precession to the Cathedral" — a piece that first became synonymous with the Rockford corps in the late 1970s — on the Fred J. Miller, Inc. Endzone stage

It was only fitting that the final moments of the 2021 season became the most-viewed moments of the year, as the DCI Celebration's finale paid tribute to the season that was, and looked forward to DCI's 50th Anniversary in 2022.
