Kotiteollisuus is a Finnish hard rock and heavy metal band that was formed in 1991 in Lappeenranta. The band released its first demo tape in 1993 under the name "Hullu ukko ja Kotiteollisuus". The shortened name and current line-up were established in 1997.
Kotiteollisuus is said to combine "furious heavy metal with Finnish sullenness". Subjects frequently touched upon in songs are the current state of the nation, religion and mankind in general. The band members have become known for their outspokenness during interviews and shows. The guitarist-vocalist Jouni Hynynen is especially known for insulting and commenting on the audience during live shows.
Kotiteollisuus is undoubtedly one of the most popular metal bands in Finland, having produced one platinum and several gold-selling albums and winning Emma-awards in 2003 and 2005 for best metal record and best DVD respectively. The band released their tenth album, Ukonhauta, on 18 February 2009.
