Belgium's NEPTUNIAN MAXIMALISM (aka NNMM) is a community of “cultural engineers” with a variable line-up, mixing drone metal with spiritual free jazz and psychedelic music. The project was initiated in 2018 by multi-instrumentalist Guillaume Cazalet (Czlt, Jenny Torse, Aksu), who brought together veteran saxophonist Jean Jacques Duerinckx (Ze Zorgs) and two drummers, Sebastien Schmit (K-Branding) and Pierre Arese (Aksu). In 2020, Stephane FDL and Lukas Bouchenot took the drums.
