Alastair Sooke spends four episodes asking why Henri Matisse, Pablo Picasso, Salvador Dali and Andy Warhol still dominate how we think about modern art. He opens with Warhol, tracing Pop Art's fixation on consumerism and celebrity through interviews that include Dennis Hopper and Carla Bruni, and through the recurring image of Marilyn Monroe that Warhol turned into a brand. The Matisse episode follows his color and flattened forms into contemporary illustration and design. For Picasso, Sooke travels through France, Spain and the United States, matching gallery works to the rebellions, wealth and relationships that produced them. The Dali episode runs from turn-of-the-century Spain to his New York years in the 1970s, treating him as both showman and serious surrealist. Each hour pairs a single artist's biography with the specific visual habits, a brushstroke, a color, a repeated motif, that later artists borrowed without always crediting.
