*FILM: Seriously, you must check out "The Effect of Dada and Surrealism on Hollywood Films of the 1930s." Sounds pretentious and grating, yes. But it's not. Not at all. The clips of films they're screening are astoundingly fun. First, you get to see two numbers from Busby Berkeley's surrealistic masterpiece Dames (1934). (Check out the musical numbers above, which feature neon violins, dancing severed heads, dizzying chorus lines, and sheer kaleidoscopic insanity.) Then some Lady in the Dark, the Marx Brothers' Duck Soup (with a reportedly Dadaist final battle scene), and Salvador Dali's famous and infamously creepy Un Chien Andalou (An Andalusian Dog) are thrown in for good measure.
