The doom metal band called WALL OF SLEEP (founded in 2001) is one of the most recognized bands of the Hungarian underground metal scene. Built on the remains of Mood (1993-2001), their traditional doom metal sound is based on twin guitar harmonies and classic heavy rock elements, which are rooted on the sounds of 70's and 80's.

They released their epic album, the Sun Face Apostoles in 2006, with the guest appearance of doom icon Scott Wino Weinrich (Saint Vitus, The Obsessed, The Hidden Hand, etc.).The year after the album called ...And Hell Followed With Him was released by the Swedish I Hate Records, so their reputation further increased.

Through some West-European tours and festivals (like Doom Shall Rise and Stoned From The Underground in Germany) they shared the stage with some great bands like Crowbar, Trouble, Mastodon, High On Fire and Darkest Hour.

Armed with a new vocalist, WALL OF SLEEP unleashed their brand new full-length, titled When Mountains Roar in 2010.
