As well as performances in Europe he has given solo recitals at most of the major concert venues in Ireland, including the National Concert Hall, the Wexford and Galway Arts Festivals, St. Michael's Church Dún Laoghaire, the Pro-Cathedral Dublin, and Trinity College Chapel. He has additionally appeared as soloist in concerto performances with a number of ensembles, including the RTE National Symphony Orchestra (in the organ symphonies of Marcel Dupré, Camille Saint-Saens and Aaron Copland), and is a former prizewinner of the Dublin International Organ Festival (now Pipeworks). He is much in demand as a vocal and instrumental accompanist.
In additions to his interests in the fields of solo and chamber music, Fergal works regularly with the RTE National Symphony and RTE Concert Orchestras, Chamber Choir Ireland and the RTE Philharmonic Choir.
