20th Century. The Firebird is one of the most popular orchestral works from the 20th Century, first composed in 1910 for the Diaghilev Ballet Russe. This work was a breakthrough for Stravinsky as well as the world of music. The Berceuse is a very quiet and mystical piece that conjures up wonderful imagery. Randy Malstrom continues with yet another great arrangement. This one is about 4+ minutes in length, for trombone octet or 8-part trombone ensemble and is suitable for advanced performers. -the publisher
