Passacaglia received it's last recording by the Bergen Philharmonic and Eivind Aadland on a Simax record released in 2002. Great work, and a very good recording. As for the symphony, the 1971 Fjeldstad reading is quite good, both when it comes to sound and interpretation. The Symphony was composed in 1942, and is a dark and pessimistic work ( but not without glimpses of hope!) due to WWII. The Symphony is divided in two parts and runs for approximately 30 minutes. It was first performed in 1945. I think it's a strong and powerful work, not quite as striking as Passacaglia, but still well worth the investment. I'm looking forward to it!
As mentioned before on this forum, cpo have recorded 4 orchestral works (I don't know more details) by Irgens-Jensen with Trondheim Symphony Orchestra and Eivind Aadland back in August 2009, but then we all know how long we have waited for that company to commercially release some of their recordings.
