Metal Music, op. 122 Michael Kibbe writes about his brass quintet, Metal Music: This work is my second essay for brass quintet, composed in 1993 and revised in 2009. The four movements are named for differing types of metal from which, historically, the instruments have sometimes been made or veneered. But these movement titles, (Brass, Silver, Copper and Gold) are only points of inspiration. The music itself presents four movements of contrasting tempos and coloration. parts included: Trumpet in Bb 1, 2, Horn in F, Trombone, Tuba
