While rising with the tide of nu-metal in the late ’90s, Disturbed actually brought something new to the genre. Part of the credit goes to frontman David Draiman’s unique vocal stylings — a blend of strained singing and a rhythmic, almost rapping, delivery. For fans of the genre, the band quickly became favorites, and their record sales show it. Out of the seven albums Disturbed released, five debuted at No. 1 on the Billboard charts. And the band’s just-released Evolution isn’t any more or less heavy than their 2000 debut, The Sickness. We’re sure fans will be able to, ahem, get down with it.
