Jonathan Hargreaves co-founded the Octandre Ensemble with composer Christian Mason in 2011, and has been at the helm of many special performances and recordings in his role as Co-Artistic Director. He has conducted the world premieres of various works by Sinan Savaşkan, in a collaboration dating back to the ensemble’s earliest days. Elsewhere in Octandre’s output, Jonathan recorded Screens, a retrospective of the British composer Frank Denyer, released on the label Another Timbre in 2022, and in 2019 he brought together the world premiere of Denyer’s epic The Fish That Became the Sun at the Huddersfield Contemporary Music Festival (having recorded that work in 2018, also on Another Timbre). He recorded an album of music by Cevanne Horrocks-Hopayian with members of the London Symphony Orchestra in 2021, following a guest appearance at LSO Soundhub. Jonathan has conducted for the Royal Scottish National Orchestra’s Film Composer Lab since 2023. From 2018 to 2022, he was Co-Artistic Director of the Nevis Ensemble, a chamber orchestra playing a broad repertoire in over 200 performances spanning a wide variety of settings, from the top of Ben Nevis to the remote isles of St Kilda.
