Nylon Beat (1995-2003) was a popular Finnish pop duo formed in Helsinki, consisting of Jonna Kosonen and Erin Koivisto (both born in 1977) . Their various hits, for example Viimeinen, Syytön and Anna Mulle, made them one of the most popular bands in Finland. After 8 years and 500 000 sold albums (8 gold and 7 platinum) they decided to quit because they wanted to try new challenges. Both have since gotten married and perform now solo by the names Jonna Geagea and Erin Anttila.
