series of works in various genres written between 1996 and 2003 focus on the life of "Mad Sweeney", a minor 7th-century king from the north of Ireland who is the subject of the ancient Irish tale Buile Shuibhne. Many other works also have an Irish focus, including the choral Nine Medieval Irish Epigrams (1973), the percussion piece Music for the Book of Kells (1990) and some works referring to the work of Irish writers James Joyce, Samuel Beckett, Gabriel Rosenstock, and Seamus Heaney. Another series of works with titles beginning on the word "Quasi ...", written since 1999 (on-going), highlights and interprets concepts such as visions or musical forms and expressions such as concertino, lamento, fuga, sarabanda, pizzicato, etc. which serve as both inspiration for the music and as creative raw material.
