This Sunday night on “The Lost Chord,” get a piece of the Rach!

It’s an hour of historic recordings of Sergei Rachmaninoff.

We’ll hear Rachmaninoff play his own “Symphonic Dances” in a newly rediscovered, fly-on-the-wall recording, captured surreptitiously at the home of Eugene Ormandy in 1940. Then Ormandy will introduce – and conduct – the Philadelphia Orchestra, in a special memorial performance of “Isle of the Dead,” given only days after the composer’s death, in 1943.

We’ll round out the hour with a literal party piece – as Rachmaninoff tosses off the Ukrainian folk song, “Bublichki,” or “Bagels,” in 1942.

These recordings are part of a 3-CD boxed set, issued by Marston Records, the record label of industry legend Ward Marston. Now based in West Chester, PA (he was born in Philadelphia in 1952), Marston is one of classical music’s most revered audio engineers. Incredibly, he has been blind since birth.

Marston’s work in restoration and conservation of historic audio has been both miraculous and rapturously received. His acclaimed remasterings have appeared on the Andante, Biddulph, Naxos, Pearl, RCA, and Romophone labels.

Then join me for an hour of Sergei Rachmaninoff in vintage recordings. That’s “Rach of Ages,” this Sunday night at 10:00 EST, on WWFM – The Classical Network and wwfm.org.
