The innovative Spanish composer Ferrer Ferran has taken Greek mythology as an inspiration for his concerto for trumpet and concert band. Hydra, the water monster decapitated by Hercules and Iolaus, terrorized the area of Lerna, near Argos. The concerto is in three contrasting sections. The first section is rhythmical and triumphant, the second is calm and melodious, and the last part provides an aggressive ending.
