Gerry O'Connor grew up in Dundalk, County Louth in a family of musicians, dancers and singers. His mother Rose (née O’Brien) taught Gerry and his siblings at home and his father Peter was a singer whose seven uncles all played music. From an early age Gerry was involved in Irish music and dance, winning numerous All Ireland titles between 1967 and 1973 in a range of formations including duet, trio and four Céili Band titles. Playing with Michael Coleman’s contemporary John Joe Gardiner in the 1970’s formed Gerry's style of music, focussing on the fluid and ornamented lyrical fiddle playing of the great Sligo masters. His own background in step dancing translates into a vibrant pulsating dance music for which he is noted; today he is regarded as one of the great fiddle players of his generation.
Gerry has played and recorded with such highly-regarded groups as Lá Lúgh and Skylark, recording four CDs on the Claddagh label. Gerry has toured and recorded with members of legendary groups including Planxty, Bothy Band, De Dannan, Boys of the Lough and The Chieftains. Gerry's solo album “Journeyman” was counted in the top five Albums of the year 2004 by the Irish Times, and was heralded as a significant milestone in recording the music of the “Oriel” region of South Ulster. He has recorded and toured with Gilles le Bigot and with The Irish Baroque Orchestra, and with others too numerous to list here. With Nuala Kennedy, Martin Quinn and Gilles le Bigot, Gerry released the album Oirialla in 2012 and currently tours with this band. Gerry is also touring with the celebrated Irish-Canadian-based group The Irish Rovers. Four times winner of The Fiddler of Oriel competition, he judges this and other competitions, and has co-founded and coordinated several festivals. Gerry teaches fiddle at the Willie Clancy Summer school and at master-classes throughout Europe. When at home he works as a violin maker and restorer.
