In 2002, a Joensuu-based Britpop group called Pool had come to a pivotal point in its career. There were no gigs and the overall motivation was low. One day, the singer Hannu Sallinen brought with him to the rehearsals a bunch of songs for which he had accidentally written lyrics in Finnish. The band started to work on them, one thing lead to another, and before the end of the year, the band had signed a record contract with a multinational record company.
After some changes in their line-up, the band was renamed as 51koodia. So far, they have released two albums: Nimetty in the beginning of 2004 and Rautaiset linnut last autumn. On Rautaiset linnut, 51koodia stretches the extremes of its expression further than ever before, finding their spiritual home both in heavy pieces and in slow, fragile, clean guitar-dominated songs.
