Lordi's third album "The Arockalypse" was released on 1 May 2006. On 20 May 2006, Lordi made history by winning the Eurovision Song Contest held in Athens with the song "Hard Rock Hallelujah", becoming the first Finnish group to win the contest and consequently the first Hard Rock / Heavy Metal band to win; Finland would then send Power Metal band Teräsbetoni in 2008. The song scored 292 points, which was an all-time points record for then. Lordi was also a semi-final number one and even got 292 points, which was historic, as they were the first competitors to win both the semi-finals and the finals. Pasi Rantanen from the band Thunderstone performed backing vocals for the performance, wearing a Gene Simmons Kiss mask.
