Described by the New Yorker as “the young Irish piano phenom”, Dublin-born pianist Isabelle O'Connell has developed an international career as soloist and chamber musician that has taken her across four continents. Since her Carnegie Hall debut recital in 2002 she has performed around the United States, Canada, Japan, Australia, New Zealand, France, Germany, Italy, U.K. and Ireland, at venues such as Lincoln Center, the Kennedy Center, Symphony Space, Baryshnikov Arts Center, Chicago Cultural Center, Cleveland Museum of Art, Detroit Art Institute and the Gilmore Keyboard Festival.

Isabelle is co-founder of Grand Band, New York’s six piano sextet, described by the New York Times as: "six of the finest, busiest pianists active in New York's contemporary-classical scene”. Isabelle also performs with the Crash ensemble, joining them for concerts in North America, Australia and in Ireland. She has also performed with John Adams at Carnegie's Zankel Hall, Meredith Monk at the Bang on a Can Summer Festival and with the ConTempo and New Zealand String Quartets.

A dynamic interpreter and energetic advocate of music by living composers, Isabelle regularly commissions and premieres new works. Her debut solo album RESERVOIR was released to critical acclaim in 2010 and features solo piano music by nine contemporary Irish composers. Her recording of Kevin Volans' Concerto for Piano and Winds with the RTE NSO was recently released on the Lyric FM label.
