Udo Kasemets (1919-2014) has been jokingly called the most famous least known composer of Estonia. There is an article about him in every respected music encyclopedia. In Canada, where Kasemets spent most of his creative life, he was named "probably the most uncompromising musician in history of Canadian music". His influence to music life especially in Toronto, in particular introducing thinking inspired by John Cage, Marhsall McLuhan and Buckminster Fuller, played an utmost importance. It is hard to overestimate his influence to the following generations. Yet in Estonia Kasemet's music has been played very little and the knowledge about Kasemets is not wide spread. To fill this gap and to celebrate Udo Kasemet's 100th anniversary (he was born exactly on November 16, 1919), to introduce his music, ideas and background, ensemble U: in collaboration with Estonian Academy of Music and Theatre is organizing conference "Explaining universe – systems, humans and arts" and concerts with music by Udo Kasemets.

Ensemble U: is currently the most active and renowned contemporary music ensemble in Estonia. It has gained recognition for its ability to perform even the most demanding works without a conductor, openness for bold experimental ideas and sensitivity for sound. In addition to Estonia U: has performed at many important international festivals. U: performs the masterworks of modern composers as well as experimental compositions. One distinct field for U: is to delve into improvisational works and perform pieces that require the rendering of non-traditional notation.
