In 2001, their major label debut album Lookbook was released on EMI/Virgin, with a more pop-oriented sound that also added more electronic effects but still retained their indie rock sensibilities. The single "It Was Easier" received heavy airplay on several radio stations, and after a large tour through Germany, the group returned with another album, 2002's Nothing Will Go Wrong. Their next album, All We Need Is Silence (2004), was more minimalistic, and the band received an art award by their hometown the same year.
In 2005, the band became part of a stage rendition of Berthold Brecht's Threepenny Opera, and the resonance was so positive that the group decided to record the songs and release them as an album. However, the Kurt Weill Foundation in New York prevented the release of the album at the last minute (the CD had already been pressed and was ready to be shipped), and ultimately, Slut were only allowed to release 5 of the 13 songs they had recorded on an EP called Die kleine Dreigroschenoper (The Small Threepenny Opera). In January 2008, the group released a new album called StillNo1, eschewing the more restrained sound of its predecessor and returning to a larger palette of sounds. ~ Christian Genzel, Rovi
