What is Improdimensija? It is a creative platform for improvisation, experimentation and education, opening the gateways to untrodden sound valleys, where not only the veterans, but also the younger generations unleash their creative powers.

After saxophonist and composer Mockūnas, known not only in but also outside of Europe, and Arūnas Zujus, the owner of and recording engineer at the MAMAstudios recording studio, joined Mikalkėnas the Improdimensija concerts started to be held in this studio in Vilnius.
