Nono's A Floresta è jovem e cheja de vida, for tape, soprano, clarinet and metal plates, is a beautiful and devastating comment on the Vietnam War. Unfortunately, the DG recording has never been issued on CD. The Mode recording just doesn't have quite the impact, although it's still worth hearing. His Un Volto del Mare is an intense, lyrical blending of electronic sounds and female vocals, which, again, has not emerged on CD as far as I know.
Interesting to see this comment, just because I’ve listened quite recently to both the DG and the Mode versions of Nono's
A Floresta è jovem e cheja de vida and I prefer the mode, which seems somehow more refined, more interior and of course, better recorded. It is an excellent piece of music IMO.
