Nostalgia is conceived by artist and designer Maria Adela Díaz, exploring the idea of water as the almost incomprehensible paradigm between life and death. A handmade sound sculpture of rainsticks can be activated by visitors in the Guatemalan pavilion, co-creating an ever-evolving performance, coupled with an exclusive soundtrack by musician and composer Joaquín Orellana.

The acoustic installation allows the audience to connect with the fact that humans are jeopardising this natural resource. It suggests that perhaps our most important objective should be to keep water free and running through rocks, vegetation, wildlife and the atmosphere.
