There are several recent compositions for orchestras of various kinds and constitutions – including commissioned work for the BBC Scottish Symphony, INSUB MetaOrchestra and the Grand Orchestre de Muzzix. Much of his current work takes the form of mixed-media assemblages, in collaboration with filmmaker/artist/writer Cherlyn Hsing-Hsin Liu.
