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 film's soundtrack at the concert in Pyongyang. The Sound of Music was chosen by Laibach as it's a well known and beloved film in the DPRK that is often used by schoolchildren to learn English. Laibach are joined by Boris Benko (Silence) and Marina Mårtensson on vocals. 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?").
