Solas (Irish: light) is an American musical group officially formed in 1996, playing Irish traditional music as well as original compositions that dabble in the country, rock, and americana genres.
Their name comes from an Irish word meaning "light". At the time, the band was made up of Séamus Egan, who had already recorded two solo albums as well as a soundtrack to a film; Winifred Horan, a member of Cherish the Ladies; John Doyle, previously a member of Susan McKeown & The Chanting House with Egan; Karan Casey and John Williams.
In June 2008 the band announced Mairead Phelan had joined the group as their new singer. In September 2010, Niamh Varian-Barry from Cork replaced Mairead Phelan as lead singer of Solas. On July 11, 2013, they announced on their Facebook page that Niamh was leaving the band and that Noriana Kennedy would be replacing her.
