French pianist, arranger, composer and conductor, Jean-Michel Defaye (b. 1932) entered the Paris Conservatoire at the mere age of ten years old. His successful compositions and arrangements were mainly for brass, Two Dances, composed in 1954, and adapted for Bass Trombone and Piano by Donald Knaub, being no exception.

With a typical performance lasting about eight minutes, Defaye's Two Dances are named Sacred Dance and Secular Dance. Defaye's understanding of the Trombone is clear throughout the work, with use of exciting techniques and contrasts. For all aspiring bass trombonists wishing to vary and expand their repertoire, Two Dances by Jean-Michel Defaye is essential.
