In May 2013, Wim Henderickx joined the Norwegian publishing house Norsk Musikkforlag in Oslo, who systematically included his entire oeuvre in its catalog: notebutikken.no. They continue to work tirelessly to publicise and distribute Wim's work.

In addition to Wim's composition classes at the Conservatories of Antwerp and Amsterdam, there was SoundMine, an initiative of Musica Impulse Centre. Since its inception in 2000, Henderickx was the principal lecturer of this annual international composition course, coaching countless young composers. After his sudden death in December 2022, editions of SoundMine are organised annually as a tribute to his work and pedagogical vision, with regulars Diederik Glorieux (composition) and Jorrit Tamminga (electronics) and new guest coaches each year. The biennial collaborations with the Antwerp Symphony Orchestra and the HERMESensemble also remain a fixture. More information about SoundMine 2026 can be found here: musica.be
Musica was also one of the commissioners of ANTIFOON in 2014, a large-scale project in which 500 professional and amateur musicians formed a living sound sculpture on the Tuikabelbrug bridge between Hasselt and Genk. Kimon Daltas wrote about it in Classical Music Magazine: ARTICLE
Musica still organises @ASTRA (1+), an interactive experience for young children based on excerpts from Henderickx's oeuvre. Diederik Glorieux and Helene Bracke created a unique performance for voice and two percussionists.

The posthumous world premiere of the Timpani Concerto took place in March 2025 with the Brussels Philharmonic in Flagey, Brussels (BE).

Wim was working on several composition assignments at the same time, which is why, after his sudden death, there were many scores on his desk, most of which were well advanced and almost finished. It would take him more than a decade to realise all his plans and ideas, and he was incredibly excited about it.

'Wim had a unique musical personality. Curiosity and searching. Always on the lookout for intense beauty.  He was impossible to ignore. Once encountered never forgotten. I was privileged to collaborate with this unique spirit on many occasions. Wim is in my heart forever.'
