From which hot even overtaking was a mellow, quiet just a cool way of playing. Of course, this album is not the birth of cool jazz. Such a thing does not exist; nor is there anyone to whom one could attribute the invention of the wheel alone. Miles Davis, however, was the one who first went in 1949 and in 1950 with a band in the studio and consistently doing something that he in this way would not expect: He was cool.
His band, and he allowed the Jazz to renew early fifties themselves. That this did not please the critics, was self-evident.
Thankfully we must no longer worry about reviews from the 50s, but just go to the CD rack, remove Birth of the Cool and enjoy.
