Roesy’s music career kicked off at 17 when he signed to Warner Chappell, and between Dublin and London recorded, co-produced and released his first album Sketch the Day, Paint the Night. His next two albums The Spirit Store and Only Love is Real were self-produced on return trips home from spending a few months at a time in cities around Europe, USA, Asia and South America. These lead to nominations for Best New Irish Act in the 2004 Meteor Awards and in the Traditional/Folk category in the 2005 Hot Press Awards.

Having received massive success with his fourth album Colour Me Colourful and a huge amount of airplay with the single 'Trailing the true star' followed. Roesy soundproofed the basement of his Amsterdam apartment where he was then living and got to work writing and recording Fable. The album was mixed in New York, where he had previously been picked up by publishers Wardlaw Banks and Downtown Music, currently promoting him in the USA.

In the Summer of 2010 after completing a tour with fellow singer/songwriter & guitarist, Albert Niland, the two went straight to the legendary Windmill Lane Studios, Dublin and lay down 12 previously recorded songs. This became the fifth album simply titled Roesy and was released as an introductory album to the Benelux region through Dutch label Mass Market Recordings.

Roesy currently lives in Melbourne, Australia and has begun writing and recording his sixth album.
