Query: A review for Marcel Duchamp: In His Own Words

Anyone who is a fan of Marcel Duchamp or interested in his works and 20th Century Art will find this video fascinating. It contains 3 sections ranging from his Cubist period to his Ready-Made objects. The video provides a lot of information about "why" Duchamp chose to create the artworks he did. Particular attention is paid to Nude Descending a Staircase, # 2, and The Large Glass, or The Bride Stripped Bare by Her Bachelors, Even. Though, in some places, it was hard to understand the artist as he spoke about his works, it is a worthwhile video to view on a period of art that is as complex to understand as the century itself was.
