The composer Maarten Altena asked me to design the invitations for his MAE ensemble. The pictures and text had to refer to the music. But that is abstract and only relates to itself. Every other explanation is far-fetched. The only limitations are space and time, both endless. We had to think about that! My friend Henk Raaff wrote the texts, which also referred to music, image and basically everything and so it could involve everything and hence form a series that in its own way became musical and mysterious.
