Frustrated by the extreme conservatism of the Russian art world, Diaghilev organized the groundbreaking "Exhibition of Russian Art" at the Petit Palais in Paris in 1906, the first major showing of Russian art in the West. Its enormous success created a Parisian fascination with all things Russian. Diaghilev organized a 1907 season of Russian music at the Paris Opéra. In 1908, Diaghilev returned to the Paris Opéra with six performances of Modest Mussorgsky's opera "Boris Godunov," starring basso Fyodor Chaliapin. This was Nikolai Rimsky-Korsakov's 1908 version (with additional cuts and re-arrangement of the scenes). The performances were a sensation, though the costs of producing grand opera were crippling.
