Máire is a musician of exceptional calibre in a number of music related disciplines.

Traditional music and musicology have featured largely in her life and have been a source of great inspiration in her work. Having obtained B.A., B.Mus. and M.A. degrees at U.C.D., she lectured there and in the College of Music, D.I.T., before embarking on a freelance career.

Máire has composed and recorded five solo albums: Angels' Candles, The Voyage of Bran, Celtic Lovers, Dreams and Visions in Irish Song - Aislingí Ceoil and Cranna Ceoil / In Full Measure.
