The Goeyvaerts String Trio was founded in 1997 by violinist Kristien Roels, violist Kris Matthynssens and cellist Pieter Stas with the aim of performing twentieth- and twenty-first-century repertoire. The trio takes its name from the Belgian composer Karel Goeyvaerts, who played an important role in the development of new music in Europe. Besides playing existing works, the ensemble is active in commissioning new string trios.
