Then we went down to his work room, in the horrible beautiful Merz grotto [the 'Merz-Haus', built by Kurt Schwitters, where broken wheels paired with matchboxes, wire lattices with brushes without bristles, rusted wheels with curious Merz cucumbers.. .How often did we 'p-lay' in this room! Schwitters called playing, considering the sweat, working. There we glued together our paper pictures, and as I tossed away one of my glued-together works one morning, Schwitters asked, 'You don't like it? Can I have it?' – 'What do you want with this failed piece of toast?' Schwitters took a good look at it and said, 'I'll put what's on top on the bottom, I'll stick a little Merz nose in this corner and I'll sign the bottom Kurt Schwitters.' And, yes indeed, this collage became a wonderful picture by Kurt Schwitters. Schwitters was a wizard, just as Hokusai was a wizard.

Concretion signifies the material process of condensation, hardening, coagulating, thickening, growing together. Concretion designates the solidification of a mass. Concretion designates curdling, the curdling of the earth and the heavenly bodies. Concretion designates solidification, the mass of the stone, the plant, the animal, the man. Concretion is something that has grown. I want my work to find it.
