Described by the Washington Post as 'Ireland's leading classical guitarist' and by Michael Dervan in the Irish Times as 'a trailblazer...when it comes to the guitar and guitar-playing in Ireland', Feeley studied at Trinity College, Dublin, Queens College of the City University, New York, and The National University of Ireland, Maynooth, where he graduated with a PhD in music. He has taught at the American Institute of Guitar, New York, Memphis State University, the Conservatory of Music, Dublin Institute of Technology and the Royal Irish Academy of Music.

In addition to his solo and chamber music concerts, Feeley has performed widely with orchestra: with The American Symphony at Carnegie Hall, the National Symphony Orchestra of Ireland, the Ulster Orchestra, and the Irish Chamber Orchestra, among others. He has won a number of prizes in international competitions, including the Special Award for interpretation in the Mauro Giuliani competition, Italy.

The American composer, Robert Newell, has also written an extended solo guitar work for him.

He is a regular performer at many international guitar festivals and has made recordings with K-Tel, Gael-Linn Records, CBA Classics, Ossiain Records, Castle Communications, a highly acclaimed CD of contemporary Irish music with Blackbox Music, England and a CD of the music of Irish composer John Buckley with the German company, Celestial Harmonies. He has also recorded with the Chieftains and famous Spanish Soprano Montserrat Caballes.
