With the three Lars-Erik Larsson symphonies now released CPO's "ongoing series" would now seem to be:
1) Johann Nepomuk David (Austria-Germany): four symphonies released out of eight.
2) Julius Rontgen (Netherlands): eleven symphonies released out of twenty-two extant.
3) Henk Badings (Netherlands): eight symphonies released out of fifteen.
4) Louis Glass (Denmark): two symphonies released out of six.
The David are being recorded by the Vienna Radio Symphony Orchestra under Johannes Wildner....but at snail's pace. The Rontgen and Badings continuation depends I suppose on the conductor David Porcelijn's commitment to them.
I am pretty pessimistic about:
5) Rudolph Simonsen (Denmark): two symphonies released out of four. These were recorded in 2006 and released in 2009 but the conductor was Israel Yinon who died in 2015.
6) Nathanael Berg (Sweden): three symphonies released out of five. These were recorded in 2006-2007 and released in 2009-2010. The conductor was Ari Rasilainen who does not seem to do much for CPO these days.
7) Edvin Kallstenius (Sweden): one symphony released (to some acclaim) out of five. However that recording by the Helsingborg Symphony Orchestra under Frank Beermann, released in 2014, was actually recorded in October 2007.
I may be wrong but my gut feeling is that CPO has lost interest in these three composers.
Maybe they should take up the Norwegian Klaus Egge, the Swede Hilding Rosenberg, the Finn Ernest Pingoud, the Pole Grazyna Bacewicz ?????
A modern recording of Klaus Egge's fine First Symphony would be great. The Karsten Andersen on Philips/Aurora is only so-so with a boxed-in recording and I don't think that the earlier but superior Gruner-Hegge recording will ever be reissued on CD.
