Want your socks blown off? How about the finale of Kalomiris' Symphony No.1 - a sort of mélange of Glière (Ilya Murometz) and Mahler (Symphony 2 finale)...

I've had a different recording of the full Symphony (by the Austrian Radio Symphony Orchestra under Mitiadews Caridis) for years, and had quite forgotten the power of the finale (which is actually rather livelier, and less stately, in my recording). It's a strong piece throughout, actually. The full details are:
Symphony No.1 " Levendia" Op.21 (1918-1920)
I. Maestoso patetico
II. Lento
III. Scherzo: Vivo
IV. Finale: Maestoso
In my recording (the provenance of which I don't know, otherwise I'd upload it) it lasts 45 minutes.
Hello Mark, I guess your recording is from the following Koch-Schwann CD

Yep, it's obviously a rip of that.
I found a second-hand copy at Amazon.de.
Oh, yes, Kalomiri's First, what a splendid work! Fortunately, before selling my LP collection, I had made transfers of those Greek LPs of his First and Second Symphony conducted by Byron Fidetzis. His Third, available on Naxos, is also very interesting and well conducted (by Fidetzis)! Incidentally, "Levendia" means "Manhood" :-)
