This book is an invitation to discover the radical and anti-establishment philosophy of the artists of Montmartre at the turn of the twentieth century. Focussing on the Arts incohérents, the Hydropathes, fumisme, the Cabaret des Quat'z'Arts and the Vachalcade, it illustrates the importance that Montmartre held as a center of the artistic avant-garde. A selection of 200 archival items and 150 works of art from the Musée de Montmartre and other public and private collections demonstrate the varied means used by the artists of the period (satire, caricature), their preferred media (posters, illustrations, songs) and their favorite places for the expression of their art (cabarets, the circus). The variety of works reproduced from the collection of the Musée de Montmartre serves as a guide to the collection and to the history of the elegant buildings, the beautiful gardens and the important artists in residence: émile Bernard, Suzanne Valadon and Maurice Utrillo.
