The 12 tracks were produced, co-written, and arranged by the duo of Larry King and John Blasucci. Among the studio musicians enlisted to participate in the recording sessions were the London Symphony Orchestra, session guitarist Michael Thompson, jazz musician Paul Jackson, Jr., Warren Hill on saxophone, percussionist Lenny Castro, drummer Kenny Aronoff of Lynyrd Skynyrd and the Smashing Pumpkins, and Todd Sucherman of Styx. Many others were also participants in the Larry King Orchestra. Worlds Apart was released under King's label MFO Records.
Reviews for the album positive, Glory Daze Music saying "As far as genre's go, Soleil Moon could fit into numerous. Smooth jazz would be one. West Coast another. 80's pop is a good fit too. The production on Worlds Apart is utterly first class, there is a depth to it that disappears out of sight, the soul and emotion displayed on all the songs is a connection very few musicians (let alone a duo) can expect to achieve in a lifetime." Another review also espoused the production quality, saying "Normally, with more or less independent releases on small labels (or no label at all) it's the production that fails the most. Not here!"
About the style, Musical Discoveries stated "the band's first album blends singer Larry King's epic rock instincts with Blasucci's sleek-flavored approach. A truly unique jazz/pop style has been used by the group in a form never achieved by any other artist."
