Grumbling Fur is a British experimental music duo formed by Daniel O’Sullivan and Alexander Tucker, whose collaboration began in 2011. Both artists have an extensive background in the UK underground music scene, with O’Sullivan known for his work with bands such as Guapo and Ulver, and Tucker recognized for his solo work and contributions to imprints like Thrill Jockey. Together, they create a hypnotic blend of electronic and acoustic elements, mixing folk influences with avant-garde sensibilities.

Their most recent release, "Furfour," arrived to critical acclaim in 2016, marking their progression into a territory that deftly balances accessibility with their more abstract instincts. Preceding this, their 2013 album "Glynnaestra" showcased a world of pastoral psychedelia infused with modular synths and layered vocals, further establishing their unique sound. Their debut, "Furrier," released in 2011, is a richly textured amalgamate of drone, psychedelia, and ambient, serving as a statement of intent for their future explorations. As Grumbling Fur, O’Sullivan and Tucker have forged a distinctive musical journey that invites listeners into an immersive, otherworldly experience.
