The Allegheny Nightstorm was a senior drum and bugle corps based in Pittsburgh and later in Butler, Pennsylvania. The corps featured former members of the General Butler Vagabonds, Pittsburgh Royal Crusaders, Steel City Ambassadors and other local corps.
- The corps was active in the DCA circuit for several years after its founding in 2000. With a small, but dedicated membership, the corps struggled and finished 16th in 2002. While the corps lacked a substantial membership base, it appears that there was a deep committment to excellence. In 2002, the Night Storm became a part of the General Butler Vagabonds organization, but internal conflicts and weak membership caused the corps to fold before the 2003 DCA season.
