Space Music: Carl Sagan - "A Glorious Dawn"

In another installment of space music, I have to help spread the word about this marvelous audiovisual creation by John Boswell, AKA melodysheep of Color Pulse Music. What he's done here is take samples and footage from Carl Sagan's "Cosmos" and Stephen Hawking's "Universe" and mixed it all into a musical tribute. What might have come off as parody in the hands of a lesser artist really conveys a sense of cosmological awe and wonder.
