nomoth, music like that spaces me out when I'm working. And by spaced-out I mean I can really focus without distraction. Stars Of The Lid - Requiem For Dying Mothers was beautiful, and that image stunning. It reminded me of Elysium in the film Gladiator ( I love that track too ).
Also, I love movie scores and particular piaono tracks as well. Tiko Lasola is one of my favorite modern composers. He composed the music for this beautiful video, as well as many others. He's on soundcloud. https://www.youtube.com/watch?v=k72jGJTC_3o&feature=emb_logo
