Rootveld and Van Elst met at the Enschede Conservatory in the Netherlands and began performing together as Duo NIHZ shortly thereafter. Since their formation, the duo has performed concerts in countries across Europe, Asia, and the Americas. Rootveld and Van Elst performed on several radio and television shows in Italy, Hungary, The Netherlands, Israel, Argentina, India and Thailand. They are noted for blending multiple genres—including Renaissance, Baroque, Romantic, avant-garde, jazz, pop, and klezmer, and for presenting music within theatrical and educational frameworks.Repertoire and collaborations

Jewish music and Holocaust music
A significant focus of Duo NIHZ's work involves the preservation and performance of Jewish music, particularly compositions originating during the Holocaust. Their programs often include music from concentration camps and ghettos, supplemented by narrative elements, archival materials, and historical context. Their efforts in this field have been recognised by institutions such as Yad Vashem in Jerusalem, where their research and performance materials are archived.In March 2025 the Duo presented extensive research on the life and music of the Dutch Jewish composer Robert Emanuel Heilbut, resulting in a book and additional three CDs.
In addition to concert performances, the duo conducts educational workshops in schools, churches, and community centers, with the aim of promoting Holocaust remembrance and combating antisemitism through music.
Cultural and educational initiatives
In 2011, Duo NIHZ established Kulturhaus NIHZ in Nordhorn, Germany. The center functions as a performance venue and educational hub, and hosts events such as the Nordhorn Guitar Festival and the Recorder Festival Nordhorn. It also houses an extensive archive of classical guitar music. Bobby Rootveld is also a composer. His works are published at publishers like Tre Fontane in Münster, Germany.The duo teaches at the Israel Conservatory of Music in Tel Aviv and offers workshops and masterclasses internationally.
