Kvelertak is a six-piece rock band from Stavanger, Norway, formed in 2007. The group comprises vocalist Erlend Hjelvik, guitarists Vidar Landa, Bjarte Lund Rolland and Maciek Ofstad, bassist Marvin Nygaard and drummer Kjetil Gjermundrød.

The band originated in May of 2004 with singer Liam Cormier and guitarist Scott Middleton, former member of Toronto metal band At The Mercy Of Inspiration. The two wanted to form a project that combined their favorite parts of bands like Refused, Black flag, Led Zeppelin and Down, among others. The lineup was rounded out with the addition of Andrew McCracken on bass and Mike Peters on drums.

Black Tusk is mostly associated with Baroness and Kylesa, for their shared hometown of Savannah, as well as for their sludge metal sound.[1][4] The band is linked to Baroness' guitarist and vocalist John Dyer Baizley, who is also a painter and creates all of Black Tusk's artwork.[2] Black Tusk's members describe their music as "swamp metal," a term that has been described by Allmusic as "the murkiest, dirtiest sludge [metal] to come out of Savannah since Kylesa".[6] The term is a reference to the climate of Savannah in relation to the music that the band create.[2] Reviewing the album Taste the Sin, Pitchfork Media stated that the band's blend of hardcore punk and stoner metal "works to capitalize on the immediacy of its chosen genres and not to bend them into obscurity."[7] Black Tusk acknowledges its punk rock origins, but prefer not to cite a list of bands that influence them because they feel that it is ineffective since they are not "trying to emulate any one band's style or any one genre's sound.

ith influences drawing from movie soundtracks, ambient artists, and heavier acts, BLACK CLOUDS has created a sound that is as equally massive, loud, crushing, and dark, as it is ambient, quiet, beautiful and mesmerizing. “Everything Is Not Going To Be OK” encompasses all of these emotions and feelings, and it leaves you feeling as though you just listened to the soundtrack to the end of the world. The last track of this debut record features Neil Fallon of CLUTCH. His voice was used for an unknown character preaching a very haunting and terrifying spoken-word, making the title of the record feel like an absolute truth, that everything will not be OK.
