Disturbed’s latest LP, Immortalized, contains a surprisingly heartfelt rendition of the Simon & Garfunkel classic “The Sound Of Silence” that you probably wouldn’t expect from the guys who made “Down With The Sickness.” Well, Disturbed brought their folk cover sickness to Conan on Monday night (Mar. 28), and the results were… pretty great, actually!

And, amazingly, “The Sound Of Silence” may become one of Disturbed’s biggest crossover hits to date. The song zooms to No. 69 on this week’s Hot 100 chart. The cover has already gone Top 5 on Billboard’s Hot Rock Songs tally.

Immortalized became another No. 1 album for Disturbed upon its release last year. The band is currently performing across North America and has dates booked through August.
