French composer Alfred Désenclos (1912-1971) described his music as romantic. His music is expressive and atmospheric as heard in his Plain-Chant Et Allegretto for Trombone and Piano. Désenclos studied at the Roubaix Conservatory and he won the 1942 Prix de Rome. His Plain-Chant Et Allegretto was published in 1965 towards the end of the composer's life. A typical performance lasts around eight minutes in which the Trombone solo line is enhanced by rhythm and technique. As expected the two movements are contrasting suitable for the advanced trombonist. For all Tromboneplayers seeking alternative and challenging repertoire Désenclos' Plain-Chant Et Allegretto makes for a riveting performance.
