The Gloaming is a contemporary Irish/American music supergroup. Its members are fiddle player Martin Hayes, sean-nós singer Iarla Ó Lionáird, hardanger fiddle player Caoimhín Ó Raghallaigh, and pianist Thomas Bartlett. Guitarist Dennis Cahill was a member until his death in June 2022.
The group was formed in 2011 and began a first tour of Ireland with a sold out performance in the National Concert Hall. Since then they have played the NCH annually, increasing to a residency of seven consecutive nights by 2017. After the release of their third studio album and a concert tour in 2019, the band announced that it would "take a break" in 2020.
They have recorded three studio albums, The Gloaming, The Gloaming 2, The Gloaming 3, and a concert recording, Live at the NCH. Thomas Bartlett, the band's pianist, produced all four albums. The first was recorded at Grouse Lodge in County Westmeath in Ireland and the second at Real World Studios near Bath, England. The Gloaming 3 was produced at Bartlett's studio in New York.
