Vocalist/pianist/composer Rufus Wainwright released “Cigarettes and Chocolate Milk,” the first track on his sophomore album Poses, in 2001. Wainwright benefited from classical piano and composition training and has carved out two career niches: a unique brand of chamber pop and opera composition. From AllMusic‘s review: the tune “combines classic Gershwin/Brian Wilson pop feels along with a strong sense of French cabaret show tunes” — nowhere more clearly than in this live version.
Starting in E major, a modulation to E minor hits at 0:50 and reverts to E major at 1:26; the pattern continues from there.
