Coudenberg Sound Box Fest 2023 - WATER 03/12


Coudenberg Sound Box Fest

Underground festival at the heart of Europe

Every Sunday from 26th November to 17th December: double concerts + visit the archeological site of the Coudenberg Palace.

Much more than a classical music festival, Coudenberg Sound Box Fest aims to reconnect its audience with Belgium's archaeological, historical and artistic heritage by bringing the remains of the Coudenberg Palace into dialogue with the eclecticism and the dynamism of its present.

From early music dating back to the 14th century, through baroque, jazz, folk and electronic music, to contemporary compositions, the subtle and invisible links between these different styles will be revealed by internationally renowned musicians from the City of Brussels and Belgium.

Music in its four elements: in search of its hidden roots

Sunday  03/12/23 – 18:30 (Doors: 18:00 - end foreseen around 21:00)

Ludovic van Hellemont (Ondes Martenot and Buchla synthesiser)

Once a classical pianist, Ludovic Van Hellemont is no longer a pigeon-holer. His devotion to both historical instruments and contemporary acoustic and electronic music has shaped him as a multi-instrumentalist and versatile sound artist. On this occasion, he will be presenting two extremely rare instruments: the Ondes Martenot, the first electronic keyboard instrument, and the Buchla synthesiser, a true monster of sound and polyrhythm. With lightness of touch, he will weave a fabric blending the music of the past with avant-garde electronic music.

The WIG Society (Matteo Gemolo - traverso, Conor Gricmanis - violin, Blanca Prieto - viola, Carlos Payan - double bass, Lisa Kokwenda Schweiger - harpsichord)

The musical journey on which The WIG Society wishes to embark its audience promises to unite the boundaries between chamber music and symphonic music by revealing the innovative sound of some unknown gems in the style of the Mannheim school (including works by Joseph Haydn, Joseph Schmitt and Wolfgang Amadeus Mozart) from the late 18th century. The Brussels-based ensemble is part of the European EEEmerging+ project and has just released an album with the Belgian production house Outhere Music and the Arcana label.
