The five-part series celebrating the January 22 release of Henryk Górecki: A Nonesuch Retrospective and the first recording of the late composer's final work, Symphony No. 4, Tansman Episodes, continues. Today, we hear from conductor Andrey Boreyko, who led the London Philharmonic Orchestra in the premiere performance and Nonesuch recording of the new piece. "I hear these chorales bringing a very special atmosphere of concentrating on one’s own life," says Boreyko, "the lives of other people, things that happened, the meaning of it all, the afterlife, is there a light at the end of the tunnel or isn’t there? I believe this symphony as a whole is trying to answer this question as well." Watch the interview here.

Rhiannon Giddens was the subject of a feature profile on CBS Sunday Morning, looking at her life in music, as a founding member of the Carolina Chocolate Drops; following her show-stopping performance at the Another Day, Another Time concert; and since the release of her Grammy-nominated solo debut album, Tomorrow Is My Turn. "How often can you witness a moment that changes a career?" says Sunday Morning's Martha Teichner of the concert. "Giddens was like a musical explosion onstage. What happened next was like an explosion in her life." Watch it here.

The Nonesuch Journal continues its five-part video series marking the forthcoming release of Henryk Górecki: A Nonesuch Retrospective and the first recording of the late composer's final work, Symphony No. 4, Tansman Episodes, by hearing from Adrian Thomas, the author of the book Górecki and of the liner notes for the new recording. "What you get in this Fourth Symphony is pretty much the widest range of Henryk's character," says Thomas. "I think he had very broad interests in terms of what constitutes the mind, what constitutes the spirit, what constitutes the soul, and that can involve earthy things as well as ethereal things, and this is what you get in the Fourth Symphony." Watch the interview here.
