On Disc One, music from Lost In Space, John Williams sets the mood with the premiere episode to what would become the most recognizable sci-fi show in history. As a lonely spaceship dodges the deadly rockets of alien enemies and barrels through outer space, lost on a crash course to nowhere, Williams' quirky melody blasts the screen, propelled by brass with wild flute lines and an electric tonality. Disc Two includes several L.I.S. episodes with exotic themes ranging from haunted lighthouses to talking vegetables.

Disc Three features tunes from Voyage to the Bottom of the Sea, where on our own planet, a sea vessel plunges into the deep, dark unknown, encountering unimaginable beasts of danger. Inventive supercomposer Jerry Goldsmith, on the cutting edge of the day's musical technology, engages viewers with a dark and foreboding, theme, full of brass and percussion as well as pre-synthesizer keyboards to produce highly effective sonorities that reflect the mysteries of the deep and the drama of the moment.

Brave explorers embark upon a massive gateway on Disc Four, a channel through which they journey through The Time Tunnel to find untold adventure and peril. There, John Williams incorporates a steady, clock-like rhythm into his distinctive score of woodwinds, electric bass and grand cymbal crashes.

Travelers find a new world on Disc Five, a Land of the Giants where immense inhabitants dwarf them to insignificance and challenge their very existence. In this score, hints of danger in the theme quickly segue to a rhythmic, upbeat sound featuring French horns and propulsive percussion to chronicle cosmic phenomena and the crash landing and to create an eerie atmosphere, foreshadowing the suspense and excitement Allen would later use for his big-screen disaster epics.

These are the FANTASY WORLDS OF IRWIN ALLEN. As a special bonus, GNP Crescendo Records has also included Disc Six, which features alternative main title themes, an extensive 38-track sound effects library, vintage radio spots and interviews with original cast members, and special Rock musical performances by Bill Mumy (Will Robinson).

Each CD includes an extensive collection of classic photos and informative liner notes that tell the unique stories of Allen's (Television) Worlds. This historic archive of treasures is packaged in a space-age chromium case and is available exclusively as a complete box set.
