"Firefly" was composed by award-winning composer Simon Dobson (b.1981) to provide an entertaining uptempo concert work for community and youth bands. This arrangement for concert band, composed in funk-rock style, and is based on the groove beat with which it opens. Dobson says, "Firefly was written as a break from my more serious music and as a hat tip to the various types of beat-orientated music I listen to." It was first performed by Oslofjord Brass in Norway and in its wind version by Harmonie Shostakovich, Switzerland.
