Presented by the Danbury Music Centre, The Charles Ives Concert Series, led by artistic director Paul Frucht and associate artistic director Jonathan Cziner returns for the final performance tonight.  The Series closes at 7:30pm in a collaboration with the Ridgefield Symphony Orchestra at the Ridgefield Playhouse. Ives Series Artist-Faculty and Guest Artists, led by the RSO Music Director will perform a program titled 'Transfiguration.'  It will feature works that transform a traditional musical idea in a new and interesting way or that transform non-musical ideas and sounds.  The four concerts featured Ives Series Guest Artists and Artist-Faculty who are recent graduates of Juilliard and several of the country's other major conservatories.
