Described as an intergalactic hybrid of contemporary and 1980s R&B, jazzy future soul and spacey pop, the album was recorded in NYC, Miami, LA, Atlanta, London, and Israel.

The subject matter ranges from a guy and a girl fighting over the same man ("He's on My Team"—nominated for Out Song of the Year) to getting caught having sex in public with another man by the cops ("Caught), to diva worship ("Fan-tastic"), to seeking independence and self-actualization ("More Than Enough," "Back To Me") to romantic and sexual intimacy ("Funk That Ship," "Intimate.")

There is also the ballad "Bashert (Meant To Be)" in which Gold incorporates his Jewish identity of having grown up as an orthodox Jew.

Frontiers magazine called Space Under Sun "a near perfect exercise in pop music that transcends sexual boundaries and labels that offers a listening experience that can be appreciated by fans of all persuasions."

The Advocate said that "Gold performs with equal parts of sly, finger-snappin' sass and earthy R&B finesse," and remarked on how "Gold has assembled an impressive posse of collaborators...to frame his voice with the crisp yet fleshy sound of a platinum-selling recording" which includes Major Accident, Desmond Child, Kahlil, Kendra Ross, Peter Amato, Steve Skinner, and Marsha Malamet.
