Halvcirkel are four musicians who met in Copenhagen. Their music captures the essence of contemporary times and human emotions, encompassing a diverse range of compositions, both created by themselves, improvised and written by others. Always exploring unique modes of expression, they collaborate with artists from diverse disciplines, including dance and theatre.

The band was established in Copenhagen 2015. From the start it built its musical voice around new ways of listening, playing, composing and recording. Collaborations included Terry Riley, Henrik Lindstrand, Hania Rani, Craig Leon, Anders Lauge Meldgaard, Madame Nielsen, Signe Lykke, Nicki Martin, and more. In 2023, they debuted a site-specific commission by Denmark's National Gallery, staged in front of Henri Matisse's ‘L'Atelier Rouge’. In Halvcirkel's previous releases they have given new life and a personal take on some of the most revered works of modern classical music in pieces by Terry Riley, Caroline Shaw, Arvo Pärt and remixed tunes of Carl Nielsen.
