These two popular vignettes from the classic American ballet Billy the Kid have been staples in the orchestral concert repertoire since their introduction in 1940. Now available for string orchestra, the music is distinctively Copland in two contrasting styles&ndash,the pastoral innocence of &ldquo,Prairie Night&rdquo, (also known as &ldquo,Card Game at Night&rdquo,) and the rhythmic, dissonant &ldquo,Celebration,&rdquo, depicting the capture of the famed outlaw.
