It all started with a simple phone call. When Mathias Heise reached out to Anton Eger with the idea of forming a band, his vision was clear: fresh, high-energy music built on groove, improvisation, and a fearless blending of genres. With the addition of pianist Rasmus Sørensen and bassist Conor Chaplin, THE ACTION 4s was born.

Meeting for the first time on a spring day in 2023, the quartet quickly discovered a natural synergy. Their debut performances that summer were met with resounding acclaim, with Politiken music editor Thomas Michelsen calling them a “supergroup” and awarding their concert at Balders Plads five hearts. Buoyed by their success, the group headed into the studio to record their eponymous debut album.

THE ACTION 4s thrives at the intersection of jazz, rock, funk, fusion, and electronica. Their music is a dynamic interplay of raw energy and masterful artistry, seamlessly blending the acoustic and the electronic. The chromatic harmonica‘s soulful tone meets the rich textures of piano and synthesizer, while the foundation laid by the electric bass and dynamic drumming creates a playful arena for ever-evolving spontaneity. Their compositions pulse with rhythm, melody and interplay, pushing the boundaries of genre and tradition to forge an exciting new direction for Danish jazz.
