I don't know how Nolan would use them (that's for him to decide), but 3 composers who have had a huge effect on me via films are John Ottman (who scored a TON of superhero films and The Usual Suspects, which is one of my fav movies of all time; seen it over 80 times)
Carter Burwell who is the Hanz Zimmer of The Coen Bros.
And Yaan Tiersen
All are very evocative and emotional. Ill post 2 examples of the latter two. Zimmer is God, but if Nolan ever did another moody, tragic, slow piece....
And Yaan is phenomenal. Very emotional, one of many great examples
Then again, Nolan and Pfister and Zimmer are all walking in step with each other, each increasing their game as the other 2 do.
