The band includes guitarist Dan Donegan, drummer Mike Wengren, lead vocalist David Draiman and bassist John Moyer.

[1] Disturbed went into hiatus in October 2011, during which the band's members focused on various side projects, and released The Lost Children, a compilation album containing previously unreleased songs.

With over 17 million records sold worldwide, six RIAA certifications for their albums (including 5× platinum for The Sickness), singles from all eight albums reaching the top ten of the Mainstream Rock chart, and two Grammy Award nominations, Disturbed ranks alongside Slipknot and Godsmack as one of the most successful rock bands of the 21st century.

[2] Before David Draiman joined Disturbed, guitarist Dan Donegan, drummer Mike Wengren and bassist Steve "Fuzz" Kmak were in a band called Brawl with vocalist Erich Awalt.

The band eventually signed with Giant Records in August 1999 and opened for Ministry at Chicago's Riviera Theatre around the same time.

[7] Before joining Marilyn Manson's 2001 European tour, bassist Steve Kmak was unable to play with the band due to a shattered ankle, caused by falling out of a fire escape outside Disturbed's rehearsal hall in Chicago.

[12] The music video for the first single from the album, titled "Prayer", was pulled from most television stations, due to perceived similarities with the September 11, 2001 attacks.

[16] After Disturbed finished the Music as a Weapon II tour, Steve Kmak was fired by the band because of "personality differences".

[21] In an interview with Launch Radio Networks, Disturbed vocalist David Draiman stated that twenty songs were recorded for the album, but only fourteen made it to the final track listing.

The tour, also dubbed a "festival", featured the bands Killswitch Engage, Lacuna Coil, and Chimaira on the main stage.

[46] On February 26, 2010, Harmonix announced a second Disturbed pack for download on the Rock Band music store, containing the 2010 remastered versions of "Voices", "The Game", and "Meaning of Life".

On April 20, 2010, roughly two months after they entered the studio, Disturbed announced that they had finished recording the album, and were ready to begin mixing it in Los Angeles, California.

[52] Disturbed headlined the first annual "Rockstar Energy Drink Uproar" tour with Avenged Sevenfold, as well as Stone Sour, Hellyeah and Halestorm, among others in late summer 2010.

[54] Around the end of that year, Disturbed announced that they would be commencing the Music as a Weapon V tour in 2011, co-headlining with Korn and guests Sevendust, In This Moment and Stillwell.

[57] On Thursday, April 28, Disturbed announced that their previously unreleased bonus track from Asylum, titled "3", would be available for download on their website.

They said that all proceeds made from the download of the song would go towards the Damien Echols Defense Fund, a benefit foundation supporting the release of the West Memphis Three.

The song "Hell" was made available for digital download on October 11, 2011, but Draiman stated on his Twitter page that there would not be a music video for it.

[59] The new Disturbed logo was also posted to their official Facebook page, along with the video of their mascot, and their profile picture changed to solid black, indicating new activity within the band.

[60] On June 22, 2015, Disturbed posted another video on Facebook, this time showing The Guy awakening from life support, as well as an 18-hour countdown on their official website, giving speculation to a definite reunion.

[66] Disturbed was announced as a direct support to Avenged Sevenfold on their UK & European tour throughout January and March 2017, alongside In Flames and Chevelle.

In June 2018, lead guitarist Dan Donegan and bassist John Moyer confirmed with sources that the new album had been completed, with 100% of the songs finished, leaving only mixing and mastering to be done.

The new album also became the first to include a guest vocalist, with Ann Wilson of hard rock band Heart lending vocals to the dark, heavy ballad "Don't Tell Me".

[84] On February 14, 2012, on his Twitter account David Draiman confirmed that he would make an appearance on VH1's That Metal Show 10th Season airing sometime that year.

[85] In December 2014, Moyer formed a new band with Scott Weiland, Ron "Bumblefoot" Thal, twins Jon and Vince Votta called Art of Anarchy, with a self-titled album released in June 2015.

[86] After the death of Weiland, the band recruited retired Creed singer Scott Stapp and recorded their second album The Madness, released in March 2017.

[87] In February 2018, Art of Anarchy members filed a lawsuit to the New York Supreme Court against Stapp for alleged failure to promote The Madness.

[99]The secret is that we were never really part of any particular trend, although we definitely benefited from the popularity of what was called nu metal at the time ... We never had the stereotypical attributes that those bands had.

"[100]Allmusic reviewer Bradley Torreano described the album Believe as "taking the sort of jump that their heroes in Soundgarden and Pantera made after their respective breakthrough records".

They have often cited their influences as Black Sabbath, Judas Priest, Metallica, Pantera, Iron Maiden, Queensrÿche, and Soundgarden.

[2][108] Disturbed's mascot, named "The Guy", was originally a drawing of a face with a large grin, as seen on the back of the album The Sickness.
