Gavin Coyle was born in Derry, Northern Ireland. His parents raised him and his four sisters amid the fallout from the troubles.  He first came to America when he was 14 years old as part of a peace project involving youths from Northern Ireland. Similar to the Ulster Project, the goal was to help teens from Northern Ireland build friendships that would otherwise not be possible with the social and religious divisions existing at home. He continued his commitment to such peace projects when he joined the Ulster Project in 1992 and came back to the States as a counselor and chaperone. When he returned home, he graduated from St. Mary's College in Belfast in 1994 with a double major in Education and Art. In 1995, he returned to the States and has been here ever since performing to sold out crowds throughout the area.

An accomplished singer and songwriter, Gavin's musical range covers both pop and folk music as well as traditional music from his homeland. His performances often reflect this versatility as he mixes traditional and original compositions. In addition to being a guitarist, he plays several other instruments including the bodhran (an Irish drum) and the flute. Gavin's musical influences are a varied lot: Elvis, Patsy Cline, Beethoven, U2, The Velvet Underground, and John Williams.

Gavin started competing as a young boy, winning many local competitions including the Derry Feisanna - one of the largest talent contests in Ireland. At the age of 14 he won the title of All-Ireland Singing Champion. He went on to perform in Andrew Lloyd Webber's Requiem, The Siege Pageant, and Noye's Fludde.
