First Movement | Concerto for Trombone and Orchestra was written in 1924 by Danish composer Launy Grondahl during his time in Italy. It was inspired by the trombone section of the Orchestra of the Casino Theatre in Copenhaguen (of which Grondahl had been a violinist since the age of thirteen). This work was premiered in Copenhaguen by the Orchestra of the Casino Theatre with soloist Vilhelm Aarkrogh, the principal trombonist of the orchestra. The work has been recorded by Joseph Alessi, Brett Baker, Hakan Björkman, Jesper Jorensen, Massimo La Rosa, Christian Lindberg, Jacques Mauger, and Branimir Slokar, among others.
