Bach and Extraterrestrials

I heard today on the radio that J. S. Bach’s Brandenburg Concerto No. 2 was one of the pieces chosen to be taken into outer space by the Voyager spacecraft, in hopes that extraterrestrials would find it. Amongst other pieces from around the world, the Brandenburg was chosen to represent Earth because of it’s optimism. Really cool.
