O.N.E. is Poland's first all-female instrumental jazz band. As an acoustic quartet, they mix lyricism and songfulness with their wild and uncompromising free jazz energy.

Monia Muc, Kamila Drabek, Patrycja Wybrańczyk and Kateryna Ziabliuk are outstanding representatives of the young generation of musicians of the Polish improvised scene. They create in the spirit of democracy – they compose and arrange their songs together.
