"Number 3: Interwoven" lasts only about three minutes. The strange collage of colors created by Harry Smith is accompanied by Dizzy Gillespie's "Guarachi Guaro". And, while I really am not a fan of art films in general, I was VERY impressed how well the film and music worked together. Oddly, however, the DVD also has an alternate score (though by whom, it doesn't say). The alternate score is very modern and unpleasant--and unless you are a glutton for punishment, I say to stick to the Gillespie score.
The film consists of various colored shapes bouncing about the screen in time to the music. The commentary on the DVD said no one is exactly sure how Smith made this film--though he claimed it was a batik process (using wax and dyes). The commentary instead says that they think he used Vaseline, tape and block designs--and added color frame-by-frame at the end. Regardless, for what it is, it is impressive and would be an interesting exhibit in a modern art gallery.
