I was raised listening to the Star Wars trilogy score by John Williams, and after that I discovered the Star Trek music (mainly the ones composed by the late, great Jerry Goldsmith and, also, James Horner). More recently, I have come to adore Holst's The Planets (the haunting "Neptune, the Mystic" is my favourite).
I was wondering, is there any other space-related orchestral music out there, that I'm not aware of yet? Maybe a tone poem, suite, etc? I've always been fascinated by space and, somehow, music that emulates its vastness and mysterious qualities attracts my liking.
