Lordi are a Finnish hard rock band, formed in 1992 by the band's lead singer, songwriter and costume maker, Mr Lordi (Tomi Petteri Putaansuu). In addition to their melodic metal music, Lordi are also known for wearing monster masks and using horror elements with pyrotechnics during concerts and music videos.
After the novelty of their 2006 Eurovision Song Contest win with Hard Rock Hallelujah had worn of fairly quickly, the band, for me, became one of those novelty acts, like GWAR, who were remembered for one or two things and not a lot else.
