Where Volume One of the Heliocentric Worlds series had predominantly featured short abstract pieces, Volume Two features longer pieces[4] performed by a smaller group,[5] making it closer in spirit to the contemporaneous The Magic City, released on Ra's own Saturn label.

"The Sun Myth" is constructed around the intertwining of Ronnie Boykins's bowed bass and Ra's electronic keyboard.

A rare alternative version – also on ESP, and with the same catalogue number – overlays African singing at the beginning and end of the piece.

The sleeve, designed by Paul Frick, features a German astronomical chart of the solar system.

Beneath it, Frick has placed Sun Ra within a pantheon of astronomers and scientists including Tycho Brahe, Leonardo da Vinci, Copernicus, Galileo and Pythagoras.
