t.A.T.u. (Russian: Тату,) was a Russian music duo that consisted of Lena Katina and Yulia Volkova. The duo was managed by Russian television producer Ivan Shapovalov while in the group Neposedi. The duo were signed to their own production company T.A. Music, following the split with Universal Music Russia, and their sub-labels Interscope Records and Neformat.
The duo established their success with their debut single "All the Things She Said", which gained acclaim from music journalists and critics, who deemed it one of the best singles in early 2000s. The video of the single, however generated controversy worldwide, showing the girls kissing in the rain in school uniforms. Along with the number-one single, the following records "Not Gonna Get Us" and "All About Us" gained success and also charted at No. 1 on other contemporary music charts.
The duo has released six studio albums; three Russian and three English. The album 200 km/h in the Wrong Lane achieved huge success worldwide and eventually became the first group ever to get the IFPI Europe platinum award for the same album in two different languages. Due to their success, the duo were recognized as one of the most successful female music acts to emerge in the early decade and have established themselves as the most successful Russian act to date.
