In the last of three programmes from the Huddersfield Contemporary Music Festival, Sarah Walker introduces highlights from the second weekend, including the Avanti Chamber Orchestra's portrait concert of Finnish electroacoustic composer Kaija Saariaho - in which soprano Dwan Upshaw gives the first UK performance of Lonh for voice and electronics - plus Ensemble Recherche's concert of Renaissance-related new music by Charles Wuorinen, Oliver Knussen, Colin Matthews and young British composers.
