The Golden Record aboard the Voyager spacecraft contains world music and sounds of the Earth with which humanity represents itself to any extraterrestrial civilizations. This book asks the big questions that the Golden Record raises. Can music live up to its reputation as the universal language in communications with the unknown? How do we fit all of human culture into a time capsule that will barrel through space for tens of thousands of years?"--
