Mairéad Ní Mhaonaigh is an Irish fiddler and the lead vocalist for the Irish folk music band Altan, which she co-founded with her husband Frankie Kennedy in 1987. Ní Mhaonaigh is recognised as a leading exponent in the Donegal fiddle tradition, and she is often considered one of the foremost singers in the Irish language, her native tongue. She was part of the Irish supergroup T with the Maggies who performed in January 2009 at Temple Bar TradFest in Dublin their first ever two concerts under that name and who released in October 2010 their debut album. After nearly 22 years with Altan, on 28 December 2008 Ní Mhaonaigh premiered in Gweedore her debut solo album Imeall which was later released worldwide in February 2009. After 29 years with Altan, in October 2016 Ní Mhaonaigh released her alternate band Na Mooneys' debut album Na Mooneys.

Eithne Pádraigín Ní Bhraonáin known mononymously as Enya, is an Irish composer and singer-songwriter. Enya is the best-selling Irish solo artist, with an estimated 80 million albums sold worldwide, and the second-best-selling music act from Ireland overall, after the rock band U2. Her music has been widely recognised for featuring multi-layers of her own vocals and instrumentation, lengthened reverb, and interwoven elements of Celtic music. The longevity and the atypical yet successful nature of Enya's career in music are notable; she has been composing her own repertoire for over four decades.
