One of the popularly cherished notions about musical genius is that its products spring sui generis from the minds of composers. Originality is, to be sure, an important quality in nearly any compositional masterpiece. But as the accumulated trove of Western art music has grown over time, its substance and traditions have provided rich stimulus to composers’ imaginations. Each of the three compositions recorded here entails, among other things, an ingenious transformation of pre-existing musical material or styles. The eight-voice, Grammy Award-winning vocal ensemble Roomful of Teeth joins the Seattle Symphony and Ludovic Morlot in an exhilarating live performance of Luciano Berio’s Sinfonia. Morlot paired Berio’s Sinfonia with Boulez’s Notations and Ravel’s La valse, creating a sonic spectrum unlike any other.
