Over the past week, the Nonesuch Journal has posted a series of videos leading to the January 22 release of the seven-disc box set Henryk Górecki: A Nonesuch Retrospective, the first recording of the his Symphony No. 4, and the first vinyl LP of the beloved 1992 Nonesuch recording of his Symphony No. 3. The previous videos include interviews with the late composer; his son Mikolaj, who completed his father’s Fourth Symphony; Adrian Thomas, who wrote the liner notes; and conductor Andrey Boreyko, who led the London Philharmonic Orchestra’s premiere and recording of Symphony No. 4.

Natalie Merchant recently stopped by the NPR studios in Washington, DC, to perform a Tiny Desk Concert for Bob Boilen and the staff at NPR and NPR Music. The intimate set included "Cowboy Romance," from her recent album Paradise Is There: The New Tigerlily Recordings; "Texas," from her 2014 self-titled record; the title song to her album Motherland; and "Weeping Pilgrim," a Protestant hymn covered on The House Carpenter’s Daughter. For that last song, Merchant led the NPR staff in a sing-along for which Boilen suggests viewers "have a tissue handy." See why in the Tiny Desk Concert here. Merchant will join Rolling Stone's Anthony DeCurtis in conversation at NYC's 92nd Street Y on February 10 and tours the US and Europe in March.

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.
