In 1893 Carpentier, dreaming as many others did about the success of the Chat Noir, hires Jules Jouy away and opens the Decadent’s concert hall. Jules Jouy (1855–1896) was one of the greatest cabaret singers of his time and one of the most verbose (he wrote songs like an apple tree grows apples, noted Georges Montorgueil). Promoted manager, he lured the best cabaret singers — Paul Delmet, Vincent Hyspa, Marcel Legay, Tiercy — from the Chat Noir, partly due to their exasperation with tightfisted Salis. This adventure lasts only two years but enables Grun to produce his first Montmartre poster thus launching his personal style hailed by Maindron: “Very lively characters stand out as silhouettes against a white background”. Some saw here Valloton’s influence; it comes straight from the shadows theater to which Grun is devoting himself. Well laid out, with a sampling of the most prominent clientele (more or less well-known figures attending a concert, notes Reims’ catalog, in 1896 under N° 693), this good poster is quite obviously a hit and triggers new commissions.
