I know it isn't a real rarity nowadays but nice to see that Danacord will be issuing a 4th set of Victor Schioler recordings containing a live recording of Palmgren's beautiful Piano Concerto no.2 (the River). The set also apparently contains Nielsen's Violin Sonata op9 but lists it with orchestra so there is some kind of misprint somewhere.

That's worth investigating. Palmgren's Second Concerto is the best of his five.
I'm sure we don't approve of gossip on this site but Schioler was the son of Victor Bendix. Bendix was much admired by women and a piano pupil of his begged him to give her a child. Bendix agreed on condition that he should have no dealings with the child. The woman broke her promise and demanded that Bendix acknowledge the child. She threatened him with a pistol which Bendix knocked out of her hand. The scandal almost forced Bendix to emigrate to Germany with his family.
