I need to read The Sheltering Sky one day, right now I don't have the time or mental energy to read a novel so I'm sampling his travel writing and short stories. I love the absolute lack of sentimentality or any well-intentioned piety in the descriptions of North Africa and the Middle East.
He wrote the music for one of the segments of Dreams Money Can Buy (1947), a collaborative film on which many of the most important Dadaists and Surrealists collaborated. It's the segment beginning around the 54 min mark. I remember watching it on Google Video, years and years before I would know who he was.
