Patricia Kopatchinskaja in search of why we play
Friday Mar 06, 2026
Friday Mar 06, 2026
This time, Bas sits down with the extraordinary musician Patricia Kopatchinskaja - someone who refuses to stay in any box. They talk about why we play the music we play, how to stay curious in a world that prefers certainty, and what it really means to find truth inside a piece of music. Patricia shares why she'd rather ask WHY than play it safe, how working with living composers keeps music alive, and why she thinks the word "interpretation" might be missing the point entirely.
A conversation for anyone who believes music is not just notes on a page - but something urgent, human, and alive.

Shaping Matter, episode 2: David Dramm and the Craft of Louis Andriessen
Saturday Dec 13, 2025
Saturday Dec 13, 2025
In this second of two episodes about De Materie (Matter) by Louis Andriessen, fellow composer David Dramm reflects on his close relationship with Andriessen and the creation of De Materie. He describes witnessing the piece’s early development, studying with Andriessen, and experiencing the premiere of De Materie in 1989 up close. Together with host Bas Wiegers, he explores the work’s signature elements - its hammer-like opening chords, mystical second movement, playful boogie-woogie references, and slowly unfolding climaxes - showing how Andriessen combined rigorous structure with raw energy, beauty, and humor.

In the first of two episodes on De Materie, we explore Louis Andriessen’s groundbreaking masterpiece with biographer Jacqueline Oskamp. We trace the influences behind this pivotal work - from the pressure of Andriessen’s earlier successes to the political and musical ideals that shaped his 1980s style. The episode highlights the piece’s structure, its bold musical logic, and the key collaborations with Jan van Vlijmen and Robert Wilson that helped form its distinctive character. We end with a preview of Episode Two, featuring a former student offering his own view on Andriessen and his legacy.

About Charles Ives, a talk with Thomas Brodhead
Sunday Jan 14, 2024
Sunday Jan 14, 2024
I speak about Charles Ives with the great Ives connoisseur Thomas Brodhead, whom I got to know when we worked on Ives’ Fourth Symphony with the Concertgebouw Orchestra back in 2012. Ives is such a fascinating composer and has been a constant inspiration in my life as a musician. At the moment, I’m preparing his piece Three Places in New England, which I get to conduct for the first time.

Today I'm spending some time with the 93 year old Theo Loevendie, one of the first living composers I worked with as a student. I'm coming back to his music after 25 years, to prepare two concerts with the Concertgebouw Orchestra. We speak about his youth, his influences, and about the two works I'm preparing: Flexio for orchestra and Six Turkish Folk Poems for singer and orchestra.

I have a chat with Rebecca Saunders, who works very closely with musicians to find the sounds she loves. We speak about the new piece (Skull) which we have just premiered at the Achtbrücken Festival, but also about other pieces and musicians who have inspired her.
I’ve woven small fragments of her music into the episode. If you want to have a proper listen to the entire pieces, the links are below.

With Johanna Zimmer, on singing in very different situations

Monday Mar 27, 2023
For this episode, I spoke with Johanna Zimmer, a wonderful soprano I had the joy of working with many times. She works as a soloist, as a chamber musician, in the choir, in opera. We speak about this versatility and why she needs it in her life. We speak about words in music and how important they are for us as musicians. At the moment, we are working with the SWR Vokalensemble on a program with music by Ligeti, Feldman and Orlando di Lasso.
The music you hear, is:

A talk with Enno Poppe
Tuesday Feb 21, 2023
Tuesday Feb 21, 2023
For this episode, I spoke with Enno Poppe. At the moment of recording, I am doing his piece Speicher with Klangforum Wien. We speak about deciding what ideas you want to put in a piece, Enno's love of idiomatic material and his close relationship to players, which is so important for the way he writes. We speak about the different roles we can have: in the case of Enno, he is not only a composer, but also a conductor, a player, and, of course, also sometimes audience. How does his persona change when his role changes? Is a conductor a different person?

In this episode, I try to describe the process of getting to know a composer I haven't worked with before. To my great joy, I finally get to work with Chaya Czernowin. I try to explain how I get into her music, I speak to her about the music, and we listen to some inspiring musicians playing her music.
