Lazzarini was born in Milan, more precisely in the Calvairate district. From a young age, he cultivated a passion for music, which led him to study piano at the Giuseppe Verdi Conservatory in Milan. He later moved into the world of hip hop, joining the Zero2 and Blocco Recordz collectives. In 2009, he took part in the annual Italian hip hop event Tecniche Perfette.

On April 14, 2017 he released his first studio album Zzala which, compared to the previous mixtapes, is characterised by a cross between trap sounds and the use of the classically inspired piano. From the album were extracted the singles "MOB", in collaboration with rappers Nitro and Salmo, and "Lario", both being certified platinum. The album was promoted through a tour divided into two seasonal legs, the Zzala Tour. In the following months, he devoted himself to the production of songs by various Italian artists including Ernia ("Disgusting"), Nitro ("Passepartout"), and Salmo ("Lunedì").

Preceded by the singles "Porto Cervo", "Gucci Ski Mask" and "Netflix", the former being certified gold, Lazza released his second studio album Re Mida which constitutes a further evolution of the artist's musical style, which almost totally embraces trap musicality.
