"Mi vendo", "Morire qui", "Triangolo", "Baratto" are still popular in Italy, and were among all disco clubs’ playlists. The late 1970s and early 1980s were years of great success for Zero's character, with the LPs Zerofobia ("Zerophobia", 1977), Zerolandia (1978), Erozero (1979), Tregua (1980), Artide Antartide (1981), Via Tagliamento (1982) and Calore (1983) topping the Italian charts. At this time Renato Zero was amongst the two or three most popular singers in Italy and his songs "Il Cielo", "Il Carrozzone", "Amico", "Più su" and "Spiagge" were already regarded, by fans and critics, as some of the best Italian songs ever. The name Zerolandia also referred to the moving theatre (a circus tent with a capacity of 5,000) in which he performed shows throughout Italy. On numerous occasions fans would participate in the gigs, made-up like Zero and dressed in his typical costumes. In 1979 Zero played himself in the movie Ciao Nì (his usual greeting to his fans, which is a term of endearment that can be roughly translated as "Hi, Dear!"). In Italy this film grossed more than the American blockbuster Superman. In 1980 he founded his own record label called Zeromania Music. The ‘80s: career dip In the 1980s he began to abandon make-up and greasepaint, but this did not rid Zero of his mania for grandeur: in the 1980 tour, for example, he entered the stage riding a white horse. In 1982 he began a collaboration with the opera director Renato Serio, who was to write the string arrangements for almost all of Zero's following LPs. In late 1982 he took part in RAI's Fantastico 3, then the most popular Italian TV show. His career continued to be successful until 1984. That year, however, his new album Leoni si nasce, that he presented in a press conference disguised as a lion and was escorted by four aborigines, was a commercial failure, even though it peaked at No. 1. His 1987 album Zero marked the lowest point of his career, peaking at No. 13 but then almost immediately disappearing from the Italian charts. 1990s: the comeback In 1991 Renato Zero participated in the Sanremo Music Festival with the song "Spalle al muro", and from that moment on his career began to rise again. In 1993 he ranked No. 1 on the Italian charts with the LP Quando non-sei più nessuno. The following year L'imperfetto repeated this success. His
