Born in Amsterdam to Irish parents in 1991, Sebastian has studied composition in Vienna with Karlheinz Essl and under Kevin O’Connell and Jonathan Nangle at the Royal Irish Academy of Music, from which he recently graduated with the highest marks ever awarded in both composition and music technology.
He has composed over sixty concert pieces and his music has been performed all over Ireland, including performances at Kaleidoscope and the Hilltown Festival, as well as in Belgium and Austria. Recent commissions have included those from the RTÉ National Symphony Orchestra, the New Ross Piano Festival and Dun Laoghaire Organ Concerts. Other performers have included the Crash Ensemble, Kirkos, The Robinson Panoramic Quartet, Benyounes Quartet, William Dowdall, Kate Ellis, Sarah Watts, Izumi Kimura, Cora Venus Lunny and Andrew Zolinsky. He has also written around five near-impossible works for his father, David Adams.
Sebastian is a busy viola player, especially active in contemporary music, and has premiered over forty works, including pieces by Gerald Barry, Raymond Deane and Ian Wilson. He is chairman of the Irish Composers’ Collective, artistic advisor to the Fishamble Sinfonia and founder and director of Kirkos.
Sebastian’s spare time is spent eating brunch he can’t afford and swimming at Hawk Cliff (named Ireland’s best sea swimming point in a recent Irish Independent poll). He also has a healthy interest in sheep.
