Pertti Kurikan Nimipäivät, known simply as PKN, was a Finnish punk band who began in a workshop run by Lyhty, a charity for adults with developmental disabilities. In 2009, Finnish director Pekka Karjalainen sought music performed by people with disabilities for the film "Vähän kunnioitusta", which tells the story of a young girl with a learning disability aspiring to live an independent and normal life.
In 2012, their fame grew as they were the main subject of The Punk Syndrome, a Finnish documentary film. The documentary, depicting the band's story from its outset to their first European tour, earned them a following in Scandinavia and Germany.
In 2014, the band performed in a charity concert with Mr. Lordi of the Finnish rock band, Lordi. The charity concert was held in Rovaniemi on 23 May 2014 for benefit of the mentally-disabled community of Mozambique and the Lapland Metkat Association. Pertti Kurikan Nimipäivät's bold and unusual take on Eurovision has been compared to that of Lordi.
They were selected to represent their home country in the Eurovision Song Contest 2015 in Vienna with the song Aina mun pitää, which finished in last place in the first semifinal.
The group broke up in 2016.
