The Day the Earth Stood Still
Star Wars: A New Hope
By the great John Williams!
My favorite is a composition that was written 100 years ago, but is as fresh and influential as ever today. The masterpiece by Gustav Holst, The Planets. The Chicago symphony does an incredible job here.
And, Manny, if you like Intersetllar, please listen to Sun by Thomas Bergensen (Two Steps from Hell). Just an inspiring, amazing work!
Yesterday marked the 40th anniversary of the Apollo 11's landing on the moon. If you were alive on July 20, 1969, you were likely doing one of two things: Watching astronaut Neil Armstrong's historic giant leap for mankind, or packing for Woodstock. Pink Floyd guitarist David Gilmour also watched the lunar landing on July 20th, but recently wrote in The Guardian that he and his bandmates were live-soundtracking the event for the BBC. The resulting jam was called "Moonhead," a song that has frequently popped up on Floyd bootlegs throughout the years but never officially released.

I got into this kind of music when I visited in Santiago Chile a couple of years ago, (listening to Radio El Conquistador) . The interest in Space is very big down there because of the significant presence all the observatories
