The Milwaukee Symphony was one of the first American orchestras to offer recordings of their live performances as digital downloads — and along with Beethoven, Brahms and Bruckner, occasionally offered more contemporary fare, as well.
For example, on today’s date in 2005, Andreas Delfs led the Milwaukee Symphony in the world premiere performance of an orchestral work they had commissioned from Puerto Rican composer Roberto Sierra, and they offered it as a download.
Sierra’s Sinfonia No. 3, La Salsa, turned to the dance music of Cuba, the Dominican Republic and his native Puerto Rico for its basic materials, referencing riffs and rhythmic patterns familiar to salsa dancers for the work’s outer movements, with a slow second movement in habañera form.
“Puerto Rican music, especially salsa and folkloric music, has been in my compositional DNA. The vitality of the rhythms and the unique way in which melodic structure merge with the rhythms has inspired me to the present day. I always remember with nostalgia my childhood experiences in the Puerto Rican countryside, and these feelings of longing are also present in my work,” he said.
