My knowledge on the Italian composer Luigi Nono is limited, and I have only this album "sofferte onde serene..." and a compilation with Berio and Maderna. I have an interest with composers of the 20th-century who used magnetic tape as part of the ensemble, and Nono is no stranger to the tape machine. Here Nono has the noted pianist Maurizio Pollini play along with magnetic tape that is haunting and very mood sturring. It's music to wait for an upcoming storm. And that storm is "a floresta èjovem e cheja de vida." A composition with magnetic tape as well as clarinet played by William O. Smith, who was an original member of Ennio Morricone's (and others) Gruppo di Improvvisazione Nuova Consonanza.
a floresta èjovem e cheja de vida" is very much rooted in the Vietnam War, and Nono was very much against that war. The texts in this piece are from various sources and mostly from the Left. A haunting work as well as the first piece on this album.
