e was born in the neighborhood of Villa del Cerro in the city of Montevideo. When he was still a kid, he began his bandoneon studies with the teacher Víctor Radamés Rodríguez (aka Vitito). His early steps in music started when he joined juvenile music groups in his area, playing at parties and kermesses.

In 1960 he was summoned by the great pianist Jorge Cirino who was putting together an orchestra in a sort of Juan D'Arienzo’s style. After a year of intensive practice they made their official debut on October 11, 1961, at the Club Ferrocarril de Peñarol and because of their beat which was similar to the one of the Rey del Compás (King of the Beat) they quickly charmed the dancing audience and soon were known as the «Uruguayan D'Arienzo» orchestra.

His professional debut was at age 17. In 1971 Cirino, the leader split with the orchestra and maestro Alberti took over the leadership until 1985. It was a successful 25-year tenure, appearing at all the dancehalls of Montevideo and of the interior of the country; playing for all the audiences of the CX10, CX14, CX16 and CX30 radio stations and on all the television channels.

The orchestra accompanied Alberto Echagüe on Radio Carve, for the audience gathered on Tacuarembó Street, and on a tour that included several dancehalls of the Uruguayan capital and of the interior. Furthermore, on several occasions, it was conducted by Juan D'Arienzo himself.

When the music group suspended its appearances in 1985, the maestro continued with the tango activity as advisor and manager of the Sexteto Bohemio, which was led by his great friend, the bandoneonist Oscar Donato and, as from 1989, he was producer of the show for tourists ‘Tango y Candombe’ at venues like the Tupi-Nambá, on Lauro Muller Street, Tanguería 40 of the Columbia Palace hotel, Vieja Luna, a restaurant with show of his own located on Rondeau Ave., and El Panorámico, among others.

In 2001 former members of previous lineups of the orchestra met again and decided to return to the scene again with the D'Arienzo style.

Firstly, there was a joint leadership by Jorge Cirino and Nelson Alberti. Maestro Cirino quit in 2005 and, since then to these days, it has been successfully led by maestro Alberti.

In 2005, in the framework of the Primer Festival Internacional de Tango de Justo Daract (province of San Luis, Argentina), they were awarded the Cóndor de Oro, and were honored as Tangueros Ilustres of San Luis. Artists from ten countries took part of that event.

In 2012 they were invited to the VI Festival Internacional de Tango de Medellín, where they were warmly welcomed by the audiences that accompanied them on the seven stages where they appeared. It was an unprecedented event for that city, because it was the first time that a Uruguayan tango orchestra visited it and, furthermore, with three excellent singers.

In 2013 he took over the leadership of the Sexteto Rey del Compás. He composed several pieces, among them, the tangos “Memoria”, “Barra fuerte”, “El primero”, “Meterete”; the candombes “Hoy ensaya la comparsa” and “Furor de candombe” and the milonga “Pinamareña” which is included in the CD Autores y compositores Uruguayos, recorded in 2014 in the Sondor studios of Montevideo.

Up to now maestro Alberti has spent more than 55 years in the show business milieu and his portrayal had to be included in Todo Tango. Welcome, maestro!
