Claudio Rocchetti new albums is a dramatic way of loosing yourself. Memoria Istruttiva is, in fact, a concept album dedicated to the painter Kaspar D. Friedrich, to the German explorer and naturalist Alexander von Humboldt and inspired by the misadventures of Vitaliano Donati, an Italian explorer/botanist died in Indian sea. Using a variety of devices such as turntables, audio cassettes, samplers, radios, and microphones, often incorporating other objects and traditional instruments, Berlin-based Rocchetti builds compelling structures that employ sound as sheer matter, mass, and impact.
