Leon Human is a British violinist based in London. He graduated with First-Class Honours from the Guildhall School of Music & Drama, where he studied under the renowned violinist Stephanie Gonley. His earlier mentors include Peter Thomas, former Leader of the City of Birmingham Symphony Orchestra, and Judith Stowe, a long-time member of Britten Sinfonia. His playing has been recognised with numerous accolades, including the Jack Petchey Award and First Prize at both the Louis Watt Memorial Solo Competition and the Stratford & East London Music Festival.

A dedicated chamber musician, Leon co-founded Quartet Concrete, winners of the prestigious St James Prize. The ensemble has appeared at venues including St James’s Piccadilly and the Barbican Centre, and has participated in festivals such as the Guildhall Chamber Music Festival and the Nantwen Chamber Music Festival. In summer 2024, the group held a residency at the Lake District Summer Music Festival, presenting a wide range of recitals and sharing the stage with Trio Shaham Erez Wallfisch and the Alkyona Quartet. During this residency, they received coaching from the Brodsky Quartet and the Heath Quartet.

Their subsequent residency in Metz with Quatuor Diotima featured performances of À vif by Arnau Gran i Romero and The Weather of It by Donnacha Dennehy. Recent highlights include debuts at Conway Hall and Opera Holland Park. Quartet Concrete also explores cross-genre collaborations, notably with artist Sienna Spiro, performing at the O2 Academy Brixton, Wilton’s Music Hall, and Villars Palace in Switzerland. Their recording of Spiro’s Butterfly Effect has surpassed 2.1 million streams, and they joined her at the Montreux Jazz Festival in July 2025.

Since leaving the quartet in September, chamber music continues to play a central role in Leon’s career. He works regularly with his duo partner, Lucy Barratt, with whom he recently helped win the Jubilee Piano Accompaniment Prize.

Leon is a core member of the award-winning contemporary ensemble Rothko Collective, winners of the 2022 Nonclassical Battle of the Bands.
