This book accompanies the first large-scale museum exhibition in the United States devoted to the work of Francis Alÿs, one of the most acclaimed artists working today. The central focus is Alÿs s Rehearsal (Ensayo) series, but a significant number of important related works from throughout Alÿs s career are also included. Alÿs s video installation Ensayo 1, 1999 2000, shows a red Volkswagen bug attempting to ascend a steep hill in Tijuana. The car s attempts are synchronized with the soundtrack of a group of Mexican danzon musicians rehearsing. Ensayo 2, 2005, is a video that shows the rehearsal of a dancer practicing a strip-tease. Ensayo 3 will be a new work made by Alÿs specifically for the exhibition and further extending the series. Other works include When Faith Moves Mountains and Song for Lupita; along with paintings, photographs, and numerous drawings. The book, written by Russell Ferguson, organizer of the exhibition, will provide an in-depth exploration of Alÿs s oeuvre, and in particular the theme of rehearsal that has run throughout his work, as well as related issues such as repetition, storytelling, and the conditions of performance.
