"On Thursday, March 8th, 2012, the Music Composition Centre at Trinity College will host a free talk by composer Sever Tipei, visiting from the University of Illinois. The talk will take place at 6pm in the Boydell Room in House 5, Trinity College."
Tipei's speciality seems to be computer-generated music.
Admission is free but tickets must be reserved in advance. (Full details are on the TCD website, linked to above.)
