Influenced by the dark atmosphere and heaviness of bands like Celtic Frost, Samael, Cathedral OR Entombed… SLUDGE recorded their first EP "Sweet Daisy" with Tomas Skogsberg at the Sunlight studios in 1996. With the support of Lee Dorian from Cathedral, this EP was released worldwide through Godhead Records (Acrimony), and started to spread the bands name. After an intense period of work, they went back to the Sunlight Studios in the end of 1997 to record their first and darkest album "The Well". Released through Headstrong Records in 1998, this album received the interest from Xy (Samael) and was followed by gigs accroos europe, featuring some cool supporting acts for bands like : MACHINE HEAD, ENTOMBED, CATHEDRAL, SAMAEL, CROWBAR, TESTAMENT, DIE KRUPPS, ANATHEMA, STUCK MOJO, SPIRITUAL BEGGARS, … As they wanted to reproduce the way they sound "live", they recorded 8 songs by themselves in their rehearsal-room at the end of 1999. The result of this « painful » experience was mixed by Fredrik Nordström in two days at the famous Fredman Studios (Gothenburg) in January 2000. The album : « Scarecrow Messiah » received a great response from european-press (Metal Hammer 6/7 - Metal Heart 9/10 - Legacy 13/15) and after the shooting of a video from the song « Scarecrow Messiah», they made about 60 shows in one year including a full and succesfull european tour with CROWBAR in may/june 2001. After this, the band took a small break when guitar player Makro started to play as official member of SAMAEL. Makro back from worldwide tours, SLUDGE started to work again on new ideas. Finally the band went back in a « real » studio in 2004 to record their coldest and most efficient work till today :« Yellow acid rain ». Recorded in one week in Switzerland and produced by Makro, the mix was once again handled by Fredrik Nordström. The impressive production of this new album reveals the amazing heaviness of the band. Massive drums are involved into death mid-tempo guitar riffing, groovy and sharp, with catchy hymns and a direct feeling. Raw and cold vocals, breathless intensity are giving to this album a unique and dark atmosphere. « Yellow acid rain » received the interest of Mighty Music who signed the band for a worldwide deal.
