I happened to be listening to the Diamonds Are Forever ultra-expanded soundtrack last night, and I must say it is an underrated Bond score.
Everyone gets their own musical theme-Q, Wint and Kidd, Blofeld, Willard Whyte, Burt Saxby, the Bond theme and the 007 theme. John Barry lets loose on his JB Seven and jazz roots, and the Vegas music makes you snap your fingers and listen for Sammy and Sinatra.
Listen especially to the last tracks at the end. There are rich shadings of themes that get more fully developed in Octopussy and A View To A Kill among others…
…Sorry, but DAF is one of the best Bond films, still!
