William Kunhardt

Artistic Director | Principal Conductor

‘Under William Kunhardt’s baton the orchestra caught the note of melancholy underlying the Ravel and set it off with 18 century ebullience…Moving in the extreme’
Michael Church, The Independent

‘Conducted by William Kunhardt, [Sibelius 7th Symphony] made you feel as if you were at the centre of an Arctic gale with frost on your chin!’
 Fiona Maddocks, The Guardian

Since his professional debut, aged 22, William has been invited to conduct orchestras and festivals across Europe, Asia and America. He is also a tireless innovator, giving concerts that have seen the average age of his orchestra’s audience fall 10 years below national statistics.
He is Principal Conductor of the Arensky Chamber Orchestra and Resident Conductor of the Piraeus Festival in Athens. Winner of the 2014 James Conlon Conducting prize at Aspen Music Festival, William was the first conducting fellow ever to be immediately re-engaged as a guest artist by Festival Director Robert Spano.

Recent guest highlights included his American Public Radio debut with Sarah Chang, Tchaikovsky and the US premiere of Mike Mills Violin Concerto with Robert McDuffie and Aspen Festival Orchestra, Rossini and Strauss with Athens Symphony Orchestra, Tchaikovsky with the Romanian Radio Orchestra, and Mendelssohn and Mozart with the Hallé in Manchester. He has also worked as assistant conductor to Sir Mark Elder for the Hallé’s recent recording of Mahler’s 6th Symphony.

With the Arensky Chamber Orchestra, William has made London debuts at the Southbank Centre, Kings Place and Cadogan Hall. He has recorded Symphonies by Beethoven and Mozart, Ravel’s Tombeau de Couperin and concerti with Jennifer Pike, Benjamin Grosvenor, Andrew Haveron and Andriy Viytovych, all for Classic FM. Following two years of 100% sales records, concert innovations including unusual formats, venues, and programming ideas, praise from the critics of the Independent, Guardian and Telegraph, William and the ACO became UK Arts Council funded for 2017. They now turn their attention to a concert series where each performance is given in a space designed from the ground up specifically for that programme.

Rowan Bell

Director of Growth | Principal 2nd Violin

An Arensky Chamber Orchestra founder member, Scottish violinist Rowan Bell spends a great deal of time thinking about the best way to chargrill the perfect steak. He believes that there is a profound symmetry between cooking and music making, and that if he had spent more time practising and less time cooking during his time at the Royal College of Music, he would not have had the foresight to found an innovative chamber orchestra with two of his best friends.

He is first violin in the Santiago Quartet, a past member of the Vardanyan Quartet, was a Park Lane Group Young Artist and has performed as a chamber musician with international artists including Jennifer Pike, Martin Fröst, Kathryn Stott, Philip Higham, Levon Chilingirian, Simon Roland-Jones and Arisa Fugita.

Rowan grew up in the Scottish Borders, beginning violin lessons at the age of six. He subsequently became leader of the National Scottish Youth Orchestra and Camerata Scotland, before gaining BMus and MMus degrees as a Douglas Downie Scholar at the Royal College of Music studying under Professor Dona Lee Croft. He has also worked extensively with Professor Béla Katona, Levon Chilingirian and Gabor Takács-Nagy. Rowan has taught on Ciaccona International Music Course, as well as being a regular teacher at the Royal College of Music Junior Department. He is also a Trustee of the Dorothy Croft Trust for Young Musicians, which provides financial assistance to talented young instrumentalists.
