In 2016 sculptures by Fred Sandback (1943-2003) were installed in the Casa Luis Barrag n, the Casa Antonio G lvez, Cuadra San Crist bal and the Casa Gilardi of Luis Barrag n (1902-88). The American minimalist and the Pritzker Prize-winning Mexican architect share a common interest in the properties of light and color; the remarkable interplay between their works, documented in photographs, is presented for the first time in this publication, with essays by Barrag n Foundation Director Federica Zanco and curator Daniel Garza Usabiaga, as well as a conversation between architect Roger Duffy, artist Amavong Panya, curator Lilian Tone and author Edward Vazquez.
