20 years of playing and 75 works commissioned specially for them over that time - the NZTrio is heading out around the country to celebrate their latest milestone this month. There are three new commissions included in three different Legacy concerts, performed by cellist Ashley Brown, violinist Amalia Hall and pianist Somi Kim. Ashley's been there from the start while Amalia and Somi joined him in a new look NZTrio four years ago. Amalia explains to Lynn Freeman that it's not just the excellence of the playing of the individual musicians that makes a great Trio. The NZTrio's Legacy 1 concert is on the 18th of May in Wellington. The Legacy 2 and 3 concerts will take place later in the year.
