Worms, an instrumental album written in collaboration with Marco Verdecchia, was born from a dream: the main themes of the songs were dreamed by Felici, jotted down upon awakening, and then arranged with Verdecchia with the intention of exploring the dream world, forming a musical narrative that draws as much from English jazz-rock and the soundtracks of composers such as Koji Kondo, Nobuo Uematsu, and Hirokazu Tanaka (in whose honor a chiptune version of the entire album was created) as from symbolic literature.
The album tells the allegorical parable of the dream: a celestial body in the metallic shape of an infant's head, named Worms, accidentally materializes a planet in his sleep and names it Niibs. On the planet, a dwarf population deforests the earth and enslaves a quadrupedal animal population (Celestial Body Worms). Worms selects an emissary on planet Earth and has him kidnapped by two ambassadors who transport him to Niibs, which has since become a desert planet (Melancholic Journey). The emissary discovers that, there on the planet, the animal population has rebelled and freed itself, but has in turn enslaved the dwarf population in retaliation (Fat Cat Dwarves and Breakchain Echo). Sitting on a dune, the emissary observes the eternal spiral on the sandy ground in which each liberation generates a new prison, but finally raises his gaze to the red sun (Planet Niibs).
