Soundtracks by Jonny Greenwood; Bodysong (2003) and There Will Be Blood (2007). Bodysong is a combination of electronic, jazz and orchestral music while There Will Be Blood is only orchestral. Boh are fantastic.
I’ve lost the link but there is a website which has mp3s of this, the Solaris (1972) Soundtrack, it is fantastic, really amazing work by Edward Artemyev. Track listing and details can be found at Soundtrack Collector.
