The Lancer Band is a big band of the Australian Army and has been serving continuously since 1891. The band is made up of members of the Australian Army who are soldiers and musicians. The Lancer Band works primarily as a big band for rehearsals and recordings, performing music from throughout the 20th and 21st century. They also perform as a smaller jazz ensemble, a rock/party band, and a marching band for Army ceremonial taskings. The band originally started as a horse-mounted brass band as part of its regiment, the Royal New South Wales Lancers, a Light Horse or cavalry regiment. Band members have deployed on international and domestic operational service duties, both as a band and in individual soldier capacities. The Lancer Band now has a significant social media profile where it continues its mission to promote the image of the regiment and the Australian Army through music and community engagement.
