As artistic director Reno called fellow musician Lelio Luttazzi, who replaced David Matalon as Head of International Production in 1956.
By collaborating with some publishers such as Suvini-Zerboni and Messaggerie Musicali, CGD was able to hire many artists who roused much success as Giorgio Consolini, Betty Curtis and Johnny Dorelli.
In 1959, Teddy Reno sold CGD to Ladislao Sugar, a publisher of Hungarian origin and future entrepreneurial owner of the Sugar Group, which was founded by Carlo Alberto Rossi's Casa Editrice Ariston, and then abandoned to buy Musical Messengers (Messaggerie Musicali).
In the same year, Peter Sugar's wife, pop star Caterina Caselli decided to establish a satellite record company, supporting non-mainstream acts like The Radio Dept, Franco Fanigliulo, Piccola Orchestra Avion Travel and Elisa.
A notable signee during this decade was the late American singer Nicolette Larson, who recorded only one album for the company, Shadows of Love.
