TOOL releases for sale ‘Fetus in Skull’ statue today. The Fetus in Skull Maquette, half-scale collectible. Inspired by the artwork for 10,000 Days and Lateralus by Alex Grey.
Never really listened to Tool so I don’t know their actual meaning behind it and don’t recall any esoteric similarities but I’m sure someone here might. If I were to guess it would be “Brain Child” or “Undeveloped Mind”. Also “Fetus=life skull=death”.
