Neptunian Maximalism is a community of 'cultural engineers' with a variable line-up. The project was initiated by Guillaume Cazalet (CZLT) and veteran saxophonist Jean-Jacques Duerinckx (Ze Zorgs) in Brussels in 2018, during a residency with drummers Sebastien Schmit (K-Branding) and Pierre Arese (AKSU). This residency produced a trilogy, dedicated to Sun, Moon and Earth, and a first album released on Homo Sensibilis Records, mixing drone metal and spiritual free jazz, and animated by a cosmic and psychedelic energy.
