ABOUT lassenne vocale
WHO WE ARE
Lassenne Vocale is a committed international chamber choir based in Brussels, bringing together passionate singers from over 20 nationalities. More than just a choir, it offers a warm, family-like community where musical excellence meets human connection.
Founded by Ivan Yohan in 2016 and born from the collaboration of talented instrumentalists from the Brussels Royal Conservatories, Lassenne Vocal reflects the rich and diverse cultural fabric of Brussels. The ensemble is named after the underground river flowing beneath the city — symbolizes the harmonious interplay between tradition and innovation that defines Brussels’ identity, both musically and culturally, and it is currently celebrating its 10th anniversary this year.
A VOCAL ENSEMBLE ROOTED IN EXCELLENCE
Lassenne Vocale remains dedicated to exploring a wide range of choral works, from the intricate polyphony of the Renaissance to contemporary compositions. The ensemble is dedicated to musical precision, artistic expression, and meaningful interpretation.
Through collaborations both in Belgium and internationally, the choir actively contributes to the vibrant choral scene and brings high-quality performances to diverse audiences.

UPCOMING EVENTS
ERIC WHITACRE CONDUCTS LASSENNE VOCALE & KAÏros
This project aims to strengthen collaboration between the Vlaams Radiokoor and amateur choirs in Brussels by creating a shared and inspiring musical experience. While the Vlaams Radiokoor already maintains strong connections in Flanders, this initiative seeks to build deeper ties within the Brussels choral community by involving talented amateur ensembles such as Lassenne Vocale and KAÏROS.
The project will highlight the music of Eric Whitacre, who has lived in Belgium for several years and shares a close artistic relationship with the Vlaams Radiokoor. Known for his passion for education and artistic exchange, Whitacre will conduct his own works, offering amateur singers the rare opportunity to perform under his direction. The Vlaams Radiokoor will present The Sacred Veil, while the participating amateur choirs will perform Lux Aurumque and Bach (arr. Sandberg) – Come Sweet Death. Scheduled for October 2, 2026, at the Abbaye de la Cambre in Brussels, the project is designed with efficient preparation in mind, encouraging choirs to rehearse independently before coming together for joint rehearsals shortly before the performance. Ultimately, the initiative seeks to foster artistic excellence, community spirit, and meaningful collaboration within Brussels’ vibrant choral scene.
Date: October 2, 2026
Place: Abbaye de la Cambre, 1050 Ixelles
Time: 8.15pm

what our collaborators say
“It has been a pleasure to work closely with Ivan Yohan, the director of Lassenne Vocale in Brussels, once again. At proyectoeLe, we are very grateful for the warm welcome and are confident that our partnership will continue. We are bringing back home unforgettable memories of Belgium.”
Carlos Cansino Pérez, conductor & composer
“Two years ago, VU Chamber Orchestra and the Lassenne Vocale choir delivered a concert of exceptionally high artistic level, performing Dobrogosz Mass! It was a huge honor to welcome such an outstanding choir to Vilnius –
the choir and orchestra created an unforgettable spiritual celebration. I hope we collaborate again soon!”
Modestas Jankūnas, conductor of Vilnius University Chamber Orchestra
“Congratulations to Lassenne Vocale and Alexis Bourdon for this beautiful and sensitive performance of my piece “Analemme”, and thank you for giving the piece its Belgian premiere! I am very grateful to Ivan Yohan for including this piece in Lassenne Vocale’s repertoire. As both composer and an aerospace engineer, it holds a special place in my work since it sets excerpts from astronomical scientific texts to music. “
Aurélian Hallopeau, composer
“It’s been wonderful working with the excellent singers of Lassenne Vocale and their inspirational director Ivan Yohan in the past few years. It was a great honour to be able to attend a service at the St Michel & St Gudula Cathedral in Brussels last year which featured the Belgian premieres of several pieces of mine, and it was fantastic to write a new work for te choir Lumen in Umbra, which they performed so well in last December. I look forward to further collaborations in the future!”
Phillip Cooke, composer
“Collaborating with Lassenne Vocale was creatively rewarding and high octane fun. Rehearsing and performing three of my Choir and Electric Guitar works with them was a highlight of my 2024 concert calender, and hearing my Umbra Animae sung in Belgium, the country where my Great Grandfather died and for whom the piece was written, was deeply moving. The concert venue was spectacular, and the Brussels audience was fully engaged. It was a truly magical experience that I hope to repeat!”
Mark Smythe, composer for film, choir and concert music
“I still vividly remember the emotion I felt during Lassenne Vocale’s performance of O magnum mysterium – which was the world premiere of the piece. Their interpretation had the rare merit of resonating deeply with the very feeling that inspired me while composing it. The piece was meant as a journey – from the heights of unreachable celestial mysteries to the depths of the human spirit – and I believe the conductor and the choir managed to translate this voyage into sound with passion, intensity, emotion, and outstanding skill.”
Giulio De Carlo, composer
