[?!] is an in-depth introduction to the artistic practice of Lea Porsager, published on the occasion of her solo exhibition STRIPPED at Moderna Museet, Stockholm. This comprehensive monograph documents Porsager’s many types of making, whether experiments, sculptures, 3D animations, or texts. Porsager’s practice persistently preserves space for instability. Through fluctuating material agency, her work meditates on excited and exhausted states—in particles as well as bodies. New and republished essays delve into Porsager’s proclivity for experimentation, speculations, and manifestations that collide different concepts of energy, knowledge, and spirituality.
