'Sap' is a concept album about consciousness in which Okay Kaya focuses her trademark combination of abstraction and wit on what happens to her mind unaccompanied, on her tendency to feel less like a human and more like the sticky secretion of a tree. After releasing 'Watch This Liquid Pour Itself', Kaya left her home in New York and moved to Europe to create and show her various interdisciplinary exhibitions. Among others, she made an installation that amplified music made underwater and an interactive sculpture based on Jungian sandplay therapy for children. Between her exhibits, Kaya recorded through lockdowns by herself in loaned studios of generous friends.
