Duo Altiler is a Belgian violin-piano duo featuring Veronique De Raedemaeker and Alexander Declercq.
‘Altiler’ recalls the tradition of gathering under the linden tree. It also refers to the location where Alexander and Veronique first met, on the street ‘An der Linde’ at the Hochschule für Musik und Tanz in Cologne, where they began playing music together.
They have performed at the Klara Festival & Festival Musiq3 Brussels, Festival van Kortrijk and Iedereen Klassiek at the Concertgebouw Brugge.
In 2023, they performed L. van Beethoven's triple concerto in a packed Elisabethzaal in Antwerp as a benefit for Mercy Ships. As Radio Klara's ‘Twintigers’, they were praised in 2024 for their contribution to ‘Iedereen klassiek’ in the Concertgebouw Brugge with the program ‘Tango and a Madhouse’.
In 2025, they won the Supernova competition organised by Radio Klara and received the audience award.
Their repertoire spans from classical to contemporary, featuring works by Beethoven,Brahms, Bartók, Debussy, Ravel, Schnittke, and Lutosławski, Auerbach, Daems and Cánovas i Parés.
Currently Duo Altiler follows the chamber music course at the Orpheus Institute. They worked on repertoire with Robert Kulek, Alasdair Beatson, Paulo Álvares, David Quiggle, José Luis Estelles, Piet Kuijken, Abdel Rahman El Bacha & Amy Norrington.
Concertgebouw Brugge on Klara's Studio Toots concert broadcast, 1 March 2024:
"An electrifying intensity! This is how we remember the concert in Klara's studio Toots by Alexander Declercq and Veronique De Raedemaeker."
Cultuurpakt, 18 October 2023, about their performance in Klankdomein, a festival presenting works by Belgian composers:
"The 1926 Sonatine by Marcel Poot (1901–1988) was also a nice surprise. Performed by violinist Veronique De Raedemaeker and pianist Alexander Declercq. ... this Sonatine has everything a good piece of music should contain. Despite being a short piece, it contains everything. It fits and was beautifully performed.
