In 1979, he started his own "Negroni Jazz Club" near Treviso, Italy. This club was important because it acted as a studio for local musicians and gave young people the opportunity  to listen to the sounds of live traditional jazz and fusion.

Alberto came back to Hollywood in 1981 and attended the "M.I. Guitar Institute of Technology", a school for professional musicians, where he became the first Italian to graduate.

Some of his teachers at this school were Joe Diorio, Pat Martino, Joe Pass, Ron Eschete and Howard Roberts.

Joe Diorio, with his innovative style, had a major influence on Alberto.

During this time period, he also met Justo Almario, a Columbian saxophonist, who contributed an even deeper understanding of Latin jazz.

Alberto then returned to Italy for a few years to play jazz performances and  also taught guitar in Dolo (Venice) at a private school, in Bassano del Grappa at the "Lilian Terry" school, in Venice at the "Suono Improvviso" and in Treviso at the "Blue Note" and "Manzato" schools.

At this time, he was part of the Keptorkestra along with the Tonolo brothers,  Mark Abrams, Paolo Pellegatti and others who were some of the best in the Italian jazz scene. An important feature of the Keptorkestra was the guest performances by such famous musicians as Steve Lacy, Paul Jeffrey and Enrico Rava.

Negroni was also part of the "Ray Mantilla Group" which included Ray Mantilla on percussion, Bruno Cesselli on piano, Gaspare Pasini on sax, Ares Tavolazzi on Bass and Massimo Manzi on drums.

In 1985, Alberto went to London to participate in a British music exposition where he demonstrated Aria guitars and Schaller guitar "tremolo" systems.
