“Master of Puppets” is a song by the American heavy metal band Metallica, released in France only on July 2, 1986 as the only single from the band’s 1986 studio album of the same name. “Master of Puppets” is also notable for its extensive use of downpicking and long instrumental section, beginning at 3:34. Although initially not commercially successful, the song is one of the band’s most famous and popular songs, frequently played at concerts.
Although, this song deals with the drugs; how drugs are controlling you and leading towards death, Adunbee from the following video covers this song with smile on her face which is not frequent to see in the case of heavy metals. Her facial expression reflects it being easier for her to play this song. However, this cover is really beautiful. Enjoy!
