Thy Disease is a Polish industrial metal band from Kraków. Their lyrics generally deal with nihilism, apocalypse, and war. The band was formed in 1999, by musicians formerly active in bands like Sceptic, Anal Stench, and Crionics. The first demo called Art of Decadence was recorded in December the same year. In 2001 Thy Disease’s first album Devilish Act Of Creation was released. It was considered as a debut of the year among readers of Metal Hammer.
