Since her New York debut recital at Carnegie’s Weill Hall in 2002, Dublin-born pianist Isabelle O’Connell has developed an international career that has taken her across four continents.

Receiving a standing ovation at her New York Debut recital at Carnegie Hall’s Weill Recital Hall in January 2002, the New York Concert Review wrote: “She has the technical prowess… and a spirit and intelligence to bring it all together.” Isabelle has a reputation for being a dynamic interpreter and energetic advocate of music by 20th and 21st century composers, regularly commissioning and premiering new works. She has worked with John Adams, John Luther Adams, Meredith Monk, Julia Wolfe, Michael Gordon, Morton Subotnick, Kevin Volans, Bunita Marcus, Donnacha Dennehy, Dan Trueman, amongst many others. In 2007, Isabelle was co-Artistic Director of “New Music, New Ireland, New York”, a concert that showcased contemporary Irish composers at Carnegie’s Weill Recital Hall. Her debut solo album RESERVOIR featuring solo piano music by contemporary Irish composers was released to critical acclaim in 2010 and the New Yorker called her “the young Irish piano phenom”.

As concerto soloist Isabelle has performed with the National Symphony Orchestra of Ireland under conductors William Eddins, Gerhard Markson and Gavin Maloney. Her recording of Kevin Volans’ Concerto No. 1 for Piano and Winds with the NSO was released on the Lyric FM label in 2014.
