Largely based on his String Quartet No.2 (1988), Christopher Rouse's Concerto per Corde (1990) is much more than a transcription of the earlier work. A significant amount of re-writing went into the Concerto, especially in the second and third movements. The Concerto retains much of the Quartet's Russian flavor, particularly its bow to composer Dmitri Shostakovich.
Rotae Passionis; a commission from the Boston Musica Viva, was completed and first performed in 1983. It is scored for seven players: flute (doubling piccolo and alto flute), clarinet (doubling E-flat and bass clarinets), percussion, piano, violin, viola and cello. The work is a veritable compendium of extended playing techniques, requiring the utmost in virtuosity from the performers. Additionally, the wind players and pianist play various percussion instruments. For purposes of this recording a second percussionist was employed to fulfill these added roles.
