"S&M" contains performances of Metallica songs with additional symphonic accompaniment, composed by Michael Kamen, who also conducted the orchestra during the concert. According to James Hetfield, the idea to combine heavy metal with an epic classical approach was Cliff Burton's idea. His love of classical music, especially of Johann Sebastian Bach, can be found in many instrumental parts and melodic characteristics in Metallica's songwriting, including songs from "Ride The Lightning" and "Master of Puppets". Kamen, who arranged and conducted the orchestral background tracks for "Nothing Else Matters", met the band at the 1992 Grammy award show for the first time, and after hearing the "Elevator version" of the song, suggested the band perform with a whole orchestra; the band, however, did not take him up on the offer until seven years later. Lars Ulrich's favorite band Deep Purple, who he colorfully inducted into the Rock and Roll Hall of Fame in 2016, is noted for having kicked off this kind of approach 30 years before, in "Concerto for Group and Orchestra" (1969).
