Born in Naples in 1950, and brought up in Milan, Gaetano Liguori precociously becomes one of the leading figures in new Italian jazz: "The key word, for us musicians", he wrote "was 'experimentation': harmonic experimentation, rhythmic experimentation, melodic experimentation, experimentation of a new context to operate in, of a new audience and new relationships with the territory".
Son of art - his father Pasquale, from the beginning of the '50s one of the most appreciated and versatile Italian jazz drummers, throws himself into the most advanced jazz developments on the peninsula - Gaetano gives life to the Idea Trio with Roberto Del Piano on base and Filippo Monito on the drums (who is then substituted by none other than Pasquale Liguori), which is one of the most active formations since the first half of the '70s in the national jazz scene, with hundreds of concerts in conventional centres and more than anything non conventional centres such as schools, factories, squares, political demonstrations and places of protest. Having graduated from the Conservatory of Milan in piano and electronic composition, Liguori is one of the protagonists of Italian jazz who has beat put to use the lesson of American free jazz, and in his pianism he reveals a particular debt towards Cecil Taylor's poetics. In November of '75, along with artists and bands that are reference points in cutting edge Italian jazz of that time like Cadmo, Andrea Centazzo, Giorgio Gaslini, Claudio Lo Caccio, Guido Mazzon, Omci, Patrizia Scascitelli, Mario Schiavo, Liguori's Idea Trio partecipates in the show “Nuove tendenze del jazz italiano” ("new trends in Italian jazz"), which, organized by the Movimento Studentesco Cultural Commission, a group of extreme leftists who has its stronghold in Milan, is held in the assembly hall occupied by the students at the Università Statale (state university). Liguori feels himself to be part of the protest and transformation movement born in '68: a movement that has also produced a new youthful mass audience that in the heart of the '70s raids(sometimes literally) at jazz concerts, attracted by its most daring and anti-conformist forms and by its socio-political implications. In Italy Liguori is among those that most generously tighten the relationship between jazz and political commitment: among the titles of the pieces that appear in his first three albums, numerous ones testify his urgency to take up a position, to react even in music to the events that he feels he's involved in.
