KLARO! is an international jazz quartet that blends European classical and folk influences with the energy of American jazz and contemporary harmonies. Their music spans grooving rhythms, poetic ballads, and dynamic swing, always delivered with passion and curiosity.

The group consists of Karolina Strassmayer (alto saxophone, alto flute), one of the world’s leading alto saxophonists and a member of the multiple Grammy-winning WDR Big Band Cologne. She is joined by Drori Mondlak (drums), known for his subtle, melodic, and rhythmically powerful style; Billy Test (piano), an inventive composer and soloist with extensive experience in jazz ensembles and also a member of the WDR Big Band; and Sam Anning (double bass), an award-winning Australian bassist with international collaborations and likewise a member of the WDR Big Band.

Together, they present new compositions and improvisations, characterized by lyrical beauty, close musical interaction, and a strong rhythmic drive.
