Cosmos: A Personal Voyage
The series is notable for its groundbreaking use of special effects,
which allowed Sagan to apparently walk through environments that were
actually models rather than full-sized sets. The soundtrack included
pieces of music provided by Greek composer Vangelis such as Alpha, Pulstar, and Heaven and Hell Part 1
(the last movement serving as the signature theme music for the show,
and is directly referenced by the title of episode 4). Throughout the
13 hours of the series it used many tracks from several 1970s albums
such as Albedo 0.39, Spiral, Ignacio, Beaubourg, and China.
The worldwide success of the documentary series also put Vangelis'
music in the homes and brought it to the attention of a global audience.
