Laxative Souls (also known as LXSS, only due to the front cover of the first two releases on cassette) is one of the first industrial power-electronics projects appeared at the beginning of 1980. He mainly worked with raw electronics, distorted vocals, concrete sounds, self assembled electronic circuits, and sample sources, such as news broadcasts, documentaries and recordings. 2 LPs and a certain amount of cassette tapes were released via his personal label Multiple Configuration, each of them being an exquisite art object, enriched by art inserts, photos, texts and strange items attached to the tape boxes and LP jackets.

Roberto died in 2022.
