It is a period of economic difficulties linked to the still immature Italian discography; the financial position stabilizes in 1948 with the entry into the society of the Armenian-born entrepreneur Krikor Mintanjan (whose surname is sometimes Italianized in Mintangian) who nominates his wife Elisabel responsible director and assumes as artistic director the nephew of the co-founder Alberto, Aurelio Airoldi, who will remain in the company until 1987, and the pianist, arranger, and composer Franco Cassano, who will remain at the direction until 1986.

In the fifties, while the Italian discography has its own identity with the birth of record companies such as RCA Italiana and CGD, new artists are produced such as Aurelio Fierro, Flo Sandon's, Roberto Murolo and Marino Marini, giving a great boost to the activity in light music.

In the sixties are promoted characters like Little Tony, Los Marcellos Ferial, Rocky Roberts, Bruno Venturini, Le Snobs, Wess, Dori Ghezzi, Fausto Papetti, Passengers, Camaleonti, Nini Rosso, I Vianella; artists who enjoy a strong support thanks to the director of the press office of the record company Luciano Giacotto who in the same years is also director of the youth music magazine Ciao Amici, as well as producer.

The Durium sensed since the fifties the importance of distributing licensed foreign music using its increasingly advanced factory in Erba; here is the distribution of international artists such as Al Caiola, Don Costa, James Brown, Paul Anka, Mouth & MacNeal, Donna Summer, Ferrante & Teicher, Dee D. Jackson, Steve Lawrence, Eydie Gormé, Don McLean, Shirley Bassey, Plastic Bertrand, Telex and many others.

At Erba, in via Trieste, the production plant where long-playing was printed and the music cassettes under the responsibility of Valsecchi and then Mario Cvek had been left since the post-war period.

Throughout the era of vinyl and audio cassettes, a good part the activity was carried out on behalf of third parties for the most famous and important Italian record companies.

Despite this in the eighties continues the activity of scouting leading to the success of many artists, including Vanadium, one of the first Italian heavy metal bands, and a young Fiordaliso that launches at the Sanremo Festival hits like Una Dirty Poetry, Oramai and I do not want not the moon.

While Rovelli will continue his career as a manager of many artists, including Vasco Rossi, the catalogs of Durium and Ariston will be at the center of legal disputes, being then sold to Ricordi and subsequently merging into the patrimony of the purchaser BMG.
