[2] He has performed in Europe, Asia, Australasia and both North and South America as a soloist.
He is closely associated with composers such as Brian Ferneyhough,[3] Michael Finnissy, Richard Barrett, Chris Dench and Liza Lim, as well as frequently performing such composers as Pierre Boulez, Helmut Lachenmann and Vinko Globokar.
