The Hapax project was born in the northern suburbs of Naples with Michele Mozzillo (vocals, bass, synth) and Diego Cardone (guitar, programming, artwork). In 2014 the two, both already known in the Neapolitan alternative environment thanks to some previous musical collaborations, sent a demo containing a couple of auditions to Valerio Lovecchio of the Swiss Dark Nights label, who immediately promoted the production of a full-length record. Stream of Consciousness, the debut album, was conceived in a few weeks, as the title itself suggests. It takes up the narrative technique used by some writers of the early 1900s. It is a visceral, spontaneous work that immediately received notable response from the public and the specialized press and which brought the duo to the stages of half of Europe. But it is with the video premiere of the single Vitriol followed shortly by the second release Cave, released in 2016, that Hapax really begin to impose itself on the international gothic scene.

Cave originates from the band's deep bond with the belly of their city, on a journey into the dark recesses full of memories of the Neapolitan underground and, at the same time, of the human soul. Unlike the previous one, it is a well thought-out album, which leads to a more marked definition of the roles and an evolution in the sound of the band thanks to the sound research experimented by Diego in the construction of atmospheres, contaminated by other genres such as drone / industrial , and from the vocal lines developed by Michele. After numerous important shows in the Old Continent, including the highly coveted WGT, in 2018 the long tour in South America with stops in the USA is the main inspiration for the third album. Diego's emotional approach to the composition of sounds changes; stylistic and dynamic needs also dictate the need for a third element on the drums, both in the studio and live, so the Campania duo decides to involve the talented Fabio Malfi, who will be replaced later by Franceso Giuliano, multi-instrumentalist and former sound engineer of the band. The conceptual element, decisive since the choice of the name of the project and substantial in Cave, becomes predominant in the last work, the landing of a journey. It is as physical as it is transcendental. Monade was released in 2019 after a long gestation in the form of a concept album, whose Leitmotiv is inability to communicate. Alessandra, another founding member of Hapax, at least for the speculative part, whose intellectual contribution could already be seen in Stream of Consciousness and in most of the texts of Cave, as well as in the name of the project, proposes an ambitious idea for the group: of Monad "the work of the unspeakability of the world which, however, plays with the senseless self-delusion of this possibility ". The album is the most introspective never realized by the band and ideally rests on the painful awareness that it is never possible to understand each other, that the communication is an artifact of the so-called "real" in a reality in which man has lost faith in the Word, understood as an expression of the Absolute Truth, e for this now without coordinates. The Monade tour, which began with the first date at the NCN festival in Deutzen (DE), unfortunately had to stop due to the lockdown imposed by the global pandemic, during which, however, the Hapax broadcast, with an excellent following, two live streams recorded and produced on CD in limited edition (again by the Swiss Dark Night label like the rest of the discography above). Hapax (borrowed from the ancient Greek hápax legómenon: "said only once" to generally mean a word that occurs only once in the entire written corpus of a language or, by extension, of a single author) condenses an idea of ​​uniqueness in the search for sounds with well-present references, yet declined in an absolutely personal way.
