Mr. Moss is a genre-blurring band led by American vocalist Nicole Fay Kupková and Czech multi-instrumentalist and producer Michal Dvořáček. Joined by a talented lineup of Czech musicians, the band fuses swing, jazz, rock, and electro into a sound that is energetic, playful, and impossible to ignore.

Their 2020 debut album High was fun, lively, and full of energy. The title track, High, was featured in the Czech film Bábovky, giving audiences a taste of their vibrant style. With the 2025 release of B!TCH via Berlin-based label Electro Swing Thing, Mr. Moss entered a new swing’n’roll era—embracing cinematic, theatrical storytelling and bold, emotionally charged music. The follow-up single Karma continues this evolution, combining drama, narrative, and theatrical flair with their signature energy.

While their recordings showcase polished production and layered arrangements, the band truly shines live. Known for high-energy performances, they’ve played major Czech festivals including Rock for People, Colours of Ostrava, Votvírák, and JamRock, transforming every stage into an immersive, unforgettable experience.
