In the year 1977, two spacecrafts (voyager 1 & 2) were sent to the outer space by NASA, each carrying a disc containing music of different styles and times.
One classical piano (or keyboard, in this case) recording was put there, Bach's prelude and fugue in C major from the second book of the well-tempered klavier, with Glenn Gould performing.
What piano piece would you choose to the vastness of space, and what is your opinion regarding the permormer choice?
