The Sound of Music was conceived when Laibach were infamously invited to perform in North Korea in 2015. The band performed several songs from the 1965 films soundtrack at the concert in Pyongyang, chosen by Laibach as its a well-known and beloved film in the DPRK and often used by schoolchildren to learn English. Laibach are joined by Boris Benko (Silence) and Marina Mrtensson on vocals and the album gives the Laibach treatment to tracks such as My Favorite Things, Edelweiss, Do-Re-Mi and Maria, here reworked as Maria / Korea (How do you solve a problem like Maria / Korea?).

While the majority of the tracks on the album are from the film, the band also included Arirang, an interpretation of a traditional Korean folk song considered the unofficial national anthem of both North and South Korea (and released recently to mark the historic summit in Singapore between President Donald Trump and the leader of North Korea, Kim Jong-un), as well as their own workout of the Gayageum, a traditional Korean zither-like string instrument performed by students from the Kum Song Music School in Pyongyang and a recording of the bands welcome speech to Korea from Mr. Ryu from the Democratic Peoples Republic of Korea Committee for Cultural Relations.

Laibachs groundbreaking performance in North Korea was documented by director, artist and cultural diplomat, Morten Traavik in the film Liberation Day (described by MOJO as a humorous, disturbing, illuminating and sometimes moving immersion into an anomalous communist mirror-world ) which is out now via ITunes following its screening for Storyville on BBC4.

The album was recorded and produced in Ljubljana, Slovenia and in Pyongyang, DPRK and represents another successful collaboration between Laibach and Silence (Primo Hladnik and Boris Benko), who previously co-created Laibachs 2006 Volk album.
