Disturbed covers 'The Sound of Silence' by Simon & Garfunkel in a darker and a more gritty tone. The track is featured in the band's latest album 'Immortalized' released last August 21, 2015 - a long break from their previous compilation album 'The Lost Children' in 2011 and 'Asylum' in 2010.

'When I cut the vocal, I had just finished tracking another song, and it was the end of my work day. I was exhausted, and I wasn't expecting to have to sing anymore... so I took a nice hit off a big fat bowl. Then Kevin played me the arrangement and he said, 'You wanna try singing to it?' And I was, like, 'I just got high! I'm stoned off my arse!' But I wound up getting back in the vocal booth for two hours, maybe more. Just vibing and going on feel.' David Draiman, frontman of Disturbed, shared his experience when recording 'The Sound of Silence.' Kevin Churko, who offered Draiman to try to sing the classic, is the band's producer.

'Immortalized' marks the 5th time that a Disturbed album landed number 1 on the Billboard 200 charts. Disturbed is the third group to such accomplish feat with regards to topping the album charts. The other two groups being Metallica and Dave Matthews Band, which had six top chart albums. In addition to that, 'Immortalized' also debuts number 1 in the Rock Albums, Alternative Albums charts and Hard Rock Albums.

'The Sound of Silence' is a classic by American folk rock duo Simon and Garfunkel which was recorded in March 1964 in their debut album 'Wednesday Morning, 3 A.M.' The song was about people who are unable to communicate emotions with each other which leads to people's inability to love. There have been many interpretations of the song with one being associated with John F. Kennedy's assassination because the song was released 3 months after.
