Birth of the Cool' became a collector's item, I think, out of a reaction to Bird and Dizzy's music. Bird and Diz played this hip, real fast thing, and if you weren't a fast listener, you couldn't catch the humor or the feeling in their music. Their musical sound wasn't sweet, and it didn't have harmonic lines that you could easily hum out on the street with your girlfriend trying to get over with a kiss.
Miles DavisI can't write anything for myself. I can write when I hear like [John] Coltrane play something; I used to write chords and stuff for him to play in one bar. I can write for other people, but I don't never write for myself.
