Brian along with his brother Diarmuid Mac Gloinn form the award-winning duo Ye Vagabonds.. They began playing music together on the streets of their hometown in Carlow and forged a style based on close harmonies and acoustic instrumentation inspired by various folk traditions. They then moved to Dublin and quickly became familiar faces around the city’s folk and blues session scene.
Having been described as “being at the fore of a new wave of Irish folk”, they won three awards at the 2019 RTÉ Radio 1 Folk Awards: Best Track (for a recording of ‘Foggy Dew’), Best Album (their 2019 album The Hare’s Lament), and Best Folk Group.
