A little known side of famous US singer Bob Dylan has gone on show in Milan this week -- a series of paintings of New Orleans that the Pulitzer Prize-winning artist produced between 2008 and 2011. The film noir-like "New Orleans" series harks back to the city as it was in the 1940s and 1950s, with one painting showing a woman trying to break up a fight between two raincoat-clad hoodlums. Dylan began painting at the height of his music career in the 1960s but has only relatively recently returned to the visual arts, publishing three collections of drawings since 1994.
