Tubist Henrik Jan Renes asked the composer to write a Wagner/Bruckner like etude which features the Low Brass in it’s most impressive form. This beautiful rendition is a great add to the Low Brass repertoire. Instrumentation 2 Tenor Trombones – 1 Bass Trombone – 1 Tuba * Can also be played with Trombone Quartet
