I am in love with the Tron: Legacy Soundtrack by Daft Punk. I like their regular stuff but this soundtrack with orchestra as well as electronic elements is just fantastic! I also love the Portal 2 Soundtrack. I was wondering what other soundtracks / artists have a similar sound to these ones. And is there a special name for this kind of genre or is it just considered electronic?
The arranger and orchestrator working with Daft Punk on Tron: Legacy is Joseph Trapanese. He has worked on a long list of movie and television soundtracks, and combining electronics with orchestra seems to be his specialty. Check out some of his other projects.
