A premiere commercial recording of Freitas Branco's 2 Melodies for strings, op.5 (1909, premiered as a set in 2006), described as influenced by Edvard Grieg (lasting 10 minutes and described- and priced as?- a digital single) is due to be released next month by Naxos. Sounds potentially interesting.
Thanks, Eric. I believe this has now been released, as you said, as a digital single.
