Passage: In contrast, the Salon Cubists built their reputation primarily by exhibiting regularly at the Salon d'Automne and the Salon des Independants, both major non-academic Salons in Paris. They were inevitably more aware of public response and the need to communicate. Already in 1910 a group began to form which included Metzinger, Gleizes, Delaunay and Leger. They met regularly at Henri le Fauconnier's studio near the Boulevard de Montparnasse. These soirees often included writers such as Guillaume Apollinaire and Andre Salmon. Together with other young artists, the group wanted to emphasise a research into form, in opposition to the Neo-Impressionist emphasis on color.
Output:
Which five people usually met at Fauconnier's studio in 1910?
