Members are rapper J-Ax (real name Alessandro Aleotti) and DJ Jad (Vito Luca Perrini). In the spoken intro of Strade di Città, it is stated that the band is named after the article of the Irish constitution guaranteeing freedom of the press, although it must be noted that article 31 of the Irish constitution is not about the freedom of the press. They probably meant the Section 31 of the Broadcasting Authority Act.
Articolo 31 was one of the first hip hop groups in Italy, releasing one of the first Italian hip hop records, Strade di città, in 1993. Soon, they signed with BMG Ricordi and started to mix their rap with pop music, obtaining great success and popularity. However, the underground hip hop scene positioned them as traitors. Their producer was Franco Godi, who also produced the music for the Signor Rossi animated series.
In 1997, DJ Gruff dissed Articolo 31 in a track titled 1 vs 2 appearing on the first album of the beatmaker Fritz da Cat, but Articolo 31's lawyers obtained a retraction of the record, and its reissue without the song.
