More importantly, to me anyway, the other two pieces -- Three Nocturnes, Op. 35bis and Vittorioso, Op. 58 were never int he CPO series (I assume never recorded at all? Correct me if I'm wrong). Will probably buy those on eClassical.
I gather that Vittorioso can be considered either Op.35bisbis (a fourth nocturne from Fanal) or the discarded finale to the 7th symphony (see http://www.musicweb-international.com/classrev/Apr99/atterberg.htm (http://www.musicweb-international.com/classrev/Apr99/atterberg.htm).)
The three nocturnes from Fanal, lasting 22 minutes, -were- broadcast by Swedish Radio in 1983 (conducted by Gunnar Staern), though. (http://smdb.kb.se/catalog/id/001899449 (http://smdb.kb.se/catalog/id/001899449) says 1987, but a search at SMDB shows earlier broadcasts by Staern of the same work in 1983 etc which I assume to be the same performances...) (Worldcat, here mirroring the Free Library of Philadelphia/Fleisher Collection I believe, does list a manuscript full score (120pp) of "Fyra nocturner/Quattro nocturni" which I assume, from the above, includes what is basically Vittorioso as the fourth nocturne. These four nocturnes have the following five titles according to the library listing:
"Flight to the hangman's hut --
Dream-march to the place of execution --
Awakening --
Battle at sunrise --
Song of freedom."
