The author narrates the artistic life of the experimental music pioneer Pietro Grossi, following all the stages of his career—from his early activities as a cellist and instrumental composer to his later work as a computer artist. Grossi’s main experiments in electronic and computer music—from the 1950s to the present—are described. Grossi has performed, recorded and taught music. He has founded musical associations and promoted the institution of conservatory courses in electronic music. His contributions to the development of new technological musical instruments and to the creation of software packages for music-processing design have been fundamental. In recent years, he has been working on new forms of artistic production oriented toward the use of personal computers in the visual arts.
