Funny side note: a film score I associate with sweltering hot heat is one most people probably would if at all associate with the opposite.
Ennio Morricone’s music for THE THING.
I received (and first listened to) the soundtrack on a sweltering hot day, it was in my early days of film score collecting, so I played it quite a few times during hot summer days. (I also saw the movie on a hot summer day when I first watched it in the theater.)
So even though the movie itself plays in the Antarctic in below freezing temperatures, the music itself still evokes those summer days.
