From The New York Times obituary, here's something I did not know, and maybe the secret of how he connected so well, bridging the classic cinematic values with contemporary taste without sounding hacky:
In 1957 he formed the John Barry Seven, a rock ’n’ roll band styled after the popular guitar-based instrumental group the Ventures. His group recorded several instrumental hits as well as “Hit and Miss,” the theme song for the popular television program “Juke Box Jury.”
As noted in a number of places, the theme for Bond comes out of the surf rock milieu. That drive, that motion.
Sadly, you only live once...but what a body of work.
