Gut is a German grindcore band, often credited as fathers of pornogrind, and known for their over-the-top vocals and morbid, pornographic imagery.  Pornogrind is defined solely on the basis of its lyrical content and unique imagery, its focus on pornographic content.  Their music, especially with their 2006 release, combines elements of goregrind and pornogrind with hip hop, hardcore punk, and electronic music.
