It’s music by the so-called “Dean of Afro-American composers” tonight on “The Lost Chord.”

William Grant Still’s “Afro-American Symphony” (1930) will be heard alongside Ulysses Kay’s “Markings” (1966), an elegy for secretary general of the United Nations Dag Hammerskjöld, and Samuel Coleridge-Taylor’s lively “Danse Nègre” from the “African Suite” (1898).

I hope you’ll join me for the grand conclusion of my month-long survey of highlights from the landmark Black Composers Series of 1974-1978, newly reissued in a handsome 10-CD boxed set, thanks to Sony Classical, on “Black to the Future, Part IV,” this Sunday night at 10:00 EST, on WWFM – The Classical Network.

But if you find the siren song of Oscar is simply too strong to resist, you can always catch the show later in the week as a webcast, along with previous installments from the series, at wwfm.org.
