Since 2019, music publisher Iduna no longer exists. Therefore a number of changes have been made with regard to the publication of Eugène’s music:
- Some Iduna books have been taken over by d’OZ publishers.
- The sale of the remaining Iduna books takes place from this website.
- All Evocation Music Publishing books (from 2015) are still for sale on www.evocationmusicpublishing.nl.
