Tiktak was a Finnish music group consisting of six school girls from northern Helsinki, who met at a band school in Helsinki. Their debut album, Friends, included songs written by Maki Kolehmainen (of Aikakone) and was a huge hit in Finland, with unusually strong sales in the rest of Europe, especially Scandinavia. The band's music was a blend of rock and pop. Each of the girls played their own instruments with the exception of Petra who was the lead singer. The band gained great domestic popularity. The band decided to break up in 2007 with the last performance in December 2007.
