The Blue Devils B are a Junior Drum Corps based in Concord, California. They act as a feeder corps to the Blue Devils. During 1973, the Blue Devils Junior Drum and Bell Corps was converted to a "B" Bugle Corps. In 1974, the Twirling Corps continued to grow and attended their first U.S. Twirling Association (USTA) National Championships in San Francisco. The Twirlers were 40 members strong at the time and were accompanied at this competition by the "B" Bugle Corps. The Twirling Corps continued to grow after their first trip to the National Championship in 1974. They won their first National Championship in 1977 and went on to win six National Corps titles.
