Michael Daves's Orchids and Violence comprises two discs with identical track listings of mostly traditional bluegrass tunes, including songs by bluegrass pioneers Bill Monroe and Ralph Stanley. The first disc has straightforward interpretations with a band of roots-music innovators: bassist Mike Bub, violinist Brittany Haas, mandolinist Sarah Jarosz, and Punch Brothers banjoist Noam Pikelny. The second includes bass, drums, and electric guitar, mostly played by Daves, with a raw, experimental rock take on those tunes.

The London Philharmonic Orchestra, led by conductor Andrey Boreyko, performs an excerpt from the fourth movement of Henryk Górecki’s Symphony No. 4, Tansman Episodes, from the 2014 world premiere performance at London's Royal Festival Hall, as heard on the album and the seven-CD set Henryk Górecki: A Nonesuch Retrospective.

Conductor Andrey Boreyko, who led the London Philharmonic Orchestra in the premiere performance and Nonesuch recording of Henryk Górecki's Symphony No. 4, Tansman Episodes, offers insight into the piece, based on his personal experiences in Poland in the early 1990s and his connection to both Górecki and Aleksander Tansman, the Polish composer for whom Górecki named the piece. Symphony No. 4 is also included in the seven-CD set Henryk Górecki: A Nonesuch Retrospective.

Adrian Thomas, author of the book Górecki, discusses his mentorship under Henryk Górecki and the circumstances that led to Górecki's son Mikolaj's completing Symphony No. 4 following his father's death. Thomas wrote the liner notes for the first recording of the piece, which is also included in the seven-CD set Henryk Górecki: A Nonesuch Retrospective.

Composer Mikolaj Górecki discusses his father Henryk Górecki's final work, Symphony No. 4. Mikolaj reflects on his relationship with his father, as son and pupil, and relates his efforts to complete the piece after his father's death. Symphony No. 4 is also included in the seven-CD set Henryk Górecki: A Nonesuch Retrospective.

Polish composer Henryk Górecki discusses his Symphony No. 3, Symphony of Sorrowful Songs, in a 1992 interview in Katowice, Poland.

The first vinyl LP of the recording is out January 22, 2016.
