Both Marcel Galiègue and Jérôme Naulais studied the Trombone at the Paris Conservatoire. Both musicians have performed in a large number of concerts and recordings and have taken part in many international Master Classes. Theircollaboration for Open Air, therefore, makes for a well-informed compilation. As suggested by the title, Open Air focuses on breath control. With a typical performance lasting around three minutes and ten seconds, this Trombonework is a delightful, alternative piece for young trombonists. Open Air is a delightful addition to the intermediate Trombone repertoire.
