Born and raised in Ovens, Co.Cork. He played music from a young age with his siblings; his father, accordionist Donncha Ó Loínsigh; and his mother, renowned singer Caitlín Ní Bheaglaoích. Summers were spent gigging in the Corca Dhuibhne peninsula of West Kerry, where Aogán learned a great deal of his music. Postgraduate studies brought Aogán to Dublin in ’97, where he recorded an album with cousin (guitarist) Gavin Ralston, and enchanting fiddler Michelle O Brien, and in 1999 Aogán received the TG4 Gradam Ceóil Young Musician of the Year award.
Aogán has since featured on a number of albums by other artists including Tallaght whistle player Gavin Whelan’s first and second albums, and Steve Wickham’s (The Waterboys) solo fiddle album. Aogán’s passion for music has had to compete in recent times with his enthusiasm for two-wheeled activity, but the arrival of three women to his life have introduced some much needed sense and sensibility .
