Robert Ellis and Jacob Leff first developed their work as producers whilst writing and recording as two thirds of indie-pop outfit Cassia, but they have since made a name for themselves in a whole different scope. Working from their custom-built studio near Macclesfield, the duo have crafted a signature sound that combines dreamy, eclectic sounds with sharp, innovative production, and their natural ear for developing music has already proven to be a winning formula.

Ellis and Leff have rapidly become highly sought-after writer/producers, collaborating with artists like Jeremy Loops, SOFY, Seb Lowe, George Moir, Amber Run, Pippa Crossland and more. Their creative journey has taken them from Berlin’s underground studios to writing sessions across Europe and the USA, honing a distinct style that bridges raw emotion and polished soundscapes.

As Cassia continues to evolve, so does their production portfolio, shaping a fresh, boundary-pushing identity that is instantly recognisable yet entirely new, blending their global experiences as an artist with the authenticity of their Northern roots.
