She was raised in a family of seven in Castlebayney, Co. Monaghan. Grainne sang with her sisters in the choir before they broadened their interests into the likes of Aretha Franklin, the Pretenders and the Rolling Stones. Around this time she discovered Fleetwood Mac, Peter Green and the voices of Stevie Nicks and Christine McVie.
She played an old acoustic guitar for a while, but the strings were too hard to hold down. After borrowing an electric guitar from her brother-in-law she knew she had found her calling.
Like nearly every Irish guitarist she is influenced by Rory Gallagher, and talks of the passion of his music, and the tender aspects of his voice and playing.
She has written music for the BBC and, following the success of her first album "Out Of The Dark" , recorded and released her second album "Test Of Time" in 2011". Check her out at her website.
