Apati was a depressive black metal / depressive rock band formed in Västerås, Sweden in the fall of 2007 by C9H13N and Obehag. In February of 2008 Professor X (called Mr. X. back then) joined the band. Patient C joined later the same year. Their first album, "Eufori", was released in June 2009 on Total Holocaust Records. Professor X got kicked out from the band in November 2008, although he contributed a bit on "Eufori" (vocals on the song "Allt jag aldrig haft").
