The debut of this duo was a concert on the 10th World Harp Congress in the Muziekgebouw aan het IJ in Amsterdam(2008). For this festival they made a program with the unique piece Figur by Wolfgang Rihms combined with especially for this occasion written pieces by Martijn Padding and Chiel Meijering. This concert made such an impression on both the audience and Brandt and Astrid that they decided to continue with this duo. A new genre was born!

As a duo Astrid and Brandt already played many concerts in countries around the world. They toured amongst others Brazil, United States, China, Singapore, Denmark, Sweden, Norway and Germany.

Because there were no pieces written for this special combination, they invited many composers to write new music for them. Besides these new compositions, Astrid and Brandt adapt existing music for other instruments for their own concerts to make a balanced and diverse program.

One of the goals of the duo is to connect with other artists and art forms to create new concepts and inspire each other. In this form they’ve created several programs, amongst which the show ‘The Aeon of Horus” with dance, which they premiered on the World Harp Congress in Sydney in 2014. They also bring programs with for example saxophonist Johan van der Linden, trombonist Jorgen van Rijen and Bart van Lier or with the Portugese Fado singer Magda Mendes en Guitarist Ward Veenstra.
