A few days ago, on the occasion of Nikolai Rimsky-Korsakov’s birthday anniversary, I was going on about his operas. This Sunday night on “The Lost Chord,” you’ll have a chance to sample one of them, as we welcome spring with selections from “The Snow Maiden.”

Based on an allegorical Russian fairy tale of humans, quasi-mythological creatures, and the eternal forces of nature, it’s the story of a star-crossed love that brings about the end of a 15-year winter. The orchestral suite – which climaxes with the “Dance of the Tumblers” – is fairly popular, but the opera, as with all of Rimsky’s 16 efforts in the form, is virtually unknown in the West.

The recording, on the Capriccio label, which features the Bulgarian Radio Symphony conducted by Stoyan Angelov, doesn’t hold a candle to the best Rimsky opera recordings by conductors like Nikolai Golovanov, but it’s enough to give a taste of what American opera lovers are missing.

I hope you’ll join me for “Thaw of the Wild,” tonight at 10 ET, with a repeat Wednesday evening at 6, or that you’ll listen to it later as a webcast at http://www.wwfm.org.
