Novák Piano Concerto & Ballets:https://www.prestomusic.com/classical/products/9814452--vit-zslav-novak-piano-concerto-signorina-gioventu-suite-nikotina-suite
Novák's Nikotina in a modern recording. But it's the suite not the complete ballet. And I think the current Supraphon Nikotina CD is a xfer from a 1985 LP.
Oliver Triendl strikes again!
Is this the first commercial recording of the piano concerto? (I know there have been a few videos.)
There was a fairly recent one on the Supraphon label, coupled with Toman and the Wood Nymph. It's pretty idiomatic as well. It came out during the pandemic.
This CPO recording of the concerto is roughly the same as the one on Supraphon. 27:37 on CPO vs 27:00 on Supraphon.
