Edition Giannozzo 1985. Edition of 100 copies.
Great conceptual work by Rheinsberg in collaboration with Harald Weller, who works with a casting machine for metal tools. Rheinsberg calls out the names of tools (like chisel, hammer, mesh, etc) and Weller in return immediately pours the liquid metal into his machine to create those tools. On the second side of the tape Weller improvises on his machine.
