Sean O'Brien is currently one of the world's leading exponents of Irish Dance Music. Over an 18 year period Sean has played at feiseanna across the US, Ireland, the UK, Europe and Australasia and has performed at every major championship including the All Irelands and World Irish Dance Championships. He is one of the most sought after feis musicians currently on the circuit due to his dynamic, rhythmic style of playing as well as his versatility in comfortably and competently moving deftly between the accordion and the piano. An accomplished Irish dancer himself, winning both State and Australian titles, Sean toured worldwide as a dancer with Riverdance's Liffey company from 2001 to 2004. Towards the end of this time he worked closely with the show's band, playing piano on his final tour in '04. In recent years, Sean has toured and recorded with numerous artists, including folk pop act '6 Day Riot' and latin funk 8 piece 'Ballalouda'. In addition, he has composed music featured in Broadway production 'Noctu', as well as stage show 'Irish Celtic'. Other of his compositions have been recorded by bands such as award winning contemporary folk group 'Kayna'.
