A cooperation between T.O.P. Orchestra and Nanagen String orchestra from Tokyo

In the past years, String Orchestra Nanagen from Tokyo gave concerts in the Concertgebouw in Amsterdam three times. In March 2019, they return, this time for a collaboration with the T.O.P. Orchestra. Their visit will be answerd by a visit from the T.O.P. Orchestra to Tokyo in July of the same year. This establishes a unique artistic collaboration between cultures geographically far apart, a great learning opportunity for orchestra members, conductor, soloists and the two orchestras’ boards. The project will be led by conductor Kent Moussault.


  • W. A. Mozart: Sinfonia concertante for violin, viola and orchestra;

October 2018 – Tchaikovsky, Bruch and Ravel led by Dominic Seldis

Arthur den Haan, both a physicist and a pianist, played Bach’s 1st piano concerto and Mozart’s 23rd piano concerto in October 2015 conducted by Dominic Seldis and an orchestra he composed himself. This inspired the founding of the T.O.P. Orchestra, which now, on October 23rd 2018 in the beautiful Stadsgehoorzaal in Leiden, will accompany Arthur in what we’re convinced is a unique, virtuoso and inspired interpretation of Tchaikovsky’s legendary 1st piano concerto, alongside more wonderful soloists in Bruch’s double concerto for clarinet, viola and orchestra,  Tchaikovsky’s Valse-Scherzo and Ravel’s Pavane pour une infante defunte! All this will be conducted by Dominic Seldis.


Listen to a fragment by Arthur from the solo part of Tchaikovsky’s 1st piano concerto:
