Raccomandata Ricevuta Ritorno

Roman progressive rock group best known for the 1972 concept album Per... un mondo di cristallo. Line-up listed in contemporary reviews: Luciano Regoli (vocals, acoustic guitar), Nanni Civitenga (guitar), Stefano Piermarioli (keyboards), Francesco Froggio (drums, percussion), Manlio Zacchia (bass), Damaso Grassi (flute, sax).

The band's only album Per... un mondo di cristallo was released in 1972; reviews note a post‑apocalyptic concept, prominent flute/keyboards/jazz elements, and that the group broke up amid pressure from a record company related to Sanremo festival participation.

Two English-language reviews discuss the band's 1972 concept album Per... un mondo di cristallo, a post‑apocalyptic story of a man returning from space. Reviewers praise the instrumentation, jazz inserts, flute and keyboards, and concept; both note the vocals as a weaker element. Recommended mainly for collectors and Italian prog enthusiasts.
