John Warner is founder and artistic director of Orchestra for the Earth and music director of Oxford Opera. The 2023–24 season saw Warner debut with the Berliner Symphoniker, Orquestra de la Comunitat Valenciana, Slovak State Philharmonic and State Philharmonia of Armenia. He has also conducted the London Symphony Orchestra and BBC Philharmonic, and works with soloists such as Thomas Hampson, James Ehnes and Wu Wei. Equally at home in the opera house, recent invitations include Glyndebourne, Palau de les Arts Reina Sofía in Valencia and Opéra national de Paris.
His pioneering work with Orchestra for the Earth takes him around Europe, giving a wide variety of concerts that bring together music and nature, collaborating with leading environmental artists, scientists and charities. A committed advocate of contemporary music, Warner has been invited to commission and conduct world premieres at the Philharmonie Luxembourg, Het Concertgebouw and, most recently, a residency at the Beijing Music Festival.
