Showcall's Role
Showcall was engaged by the United States Department of State to commemorate the 75th anniversary of the signing of the North Atlantic Treaty Organization (NATO) agreement, held in the Andrew W. Mellon Auditorium. Showcall mapped the building’s interior, transforming the space through immersive projection mapping that honored the agreement’s founding nations and original signatories, while delivering comprehensive audio and video design and managing full international broadcast coverage. The team also managed the full broadcast transmission to media outlets worldwide.

Overview
To commemorate the 75th anniversary of the signing of the NATO agreement, the United States Department of State engaged Showcall to transform Washington, DC’s historic Andrew W. Mellon Auditorium into the centerpiece of a global celebration. Unlike traditional government summits, the program was conceived as a tribute rather than a meeting, featuring live musical performances, vocal ensembles, commemorative films, and speeches honoring the alliance’s enduring legacy.

Impact
The result was a visually striking and emotionally resonant tribute that blended technology, history, and artistry. By reimagining the iconic Andrew W. Mellon Auditorium through projection mapping and immersive production design, Showcall created a celebration that honored NATO’s legacy while highlighting the alliance’s continued unity and global relevance.
