The Band of The Adjutant General's Corps was formed on 6 April 1992 in Buller Barracks, Aldershot, with the majority of its musicians being found from the former band of the Women's Royal Army Corps. In August 1995, the band moved to its permanent station in Worthy Down, Hampshire, and the home of the Adjutant General's Corps.

It was founded from the amalgamation of The Royal Military Police, The Royal Army Pays Corps, The Royal Army Educational Corps, and The Army Legal Corps, together with elements of The Royal Army Ordnance Corps, The Women's Royal Army Corps and other Arms and Services of the Army. With over 1000 officers and 6000 soldiers, the Adjutant General's Corps is about 7% of the British Army, and currently over 14% of the Corps are on operations serving in almost every unit of the Army throughout the world.

During its brief history, the band has undertaken tours of duty at Sandhurst, performed at many high profile engagements such as Buckingham Palace Garden Parties and Wimbledon Tennis Finals, as well as supporting the Corps in Germany, Northern Ireland, Cyprus and the UK. The band has toured the USA, Spain, Italy, Denmark and Finland. In August 1999, the band deployed in its operational role to Kosovo for six months.

In addition to performing as a marching and concert band, the musicians provide ensembles and groups such as a Fanfare Team, Brass Quintet, Woodwind Quintet, Jazz Ensemble, Pop Group and Big Band. The spectrum of music covered is very wide ranging from classical to jazz, film and popular music.
