This was a few years before Jurassic Park and a much more family-friendly animated feature.

Horner starts out "The Great Migration" with a gradually building orchestral theme with his trademark arpeggiated strings. In the second half of the cue he directs the music to a jauntier and adventurous sound with some soaring lines and angelic choir.

A similar feel begins the long "Sharptooth and the Earthquake" cue with the heavenly sounds giving away to more earthy brass and percussion, which outline tension and action before relaxing into sinuous modalities. Soon enough it's danger time again with propulsive orchestral action that can stand with the best of John Williams.

"Whispering Winds" is another long track, beginning in a low-key and wind instrument-driven fashion with the cue being taken over by the choir again. Horner has written some absolutely lovely, lyrical pieces for this film.

There are moments of humor in "Foraging for Food" with different parts of the orchestra popping up here and there, bringing us eventually to a spare and staccato passage.

This register, somewhere in between playful and apprehensive, is picked up for the beginning of "Journey of the Dinosaurs", which features tuba.

For "Separate Paths", the strings create a beautiful atmosphere of wonder but yield to darker orchestral colors that sound menacing, soon to be replaced by the ethereal choir. Then there's more string writing and some very sharp percussion stings.

The longest track here, "The Rescue/Discovery of the Great Valley" is almost 13 minutes long. As you can imagine, there's a lot going on here. It starts with the choir before going into sounds of danger and action, which perhaps includes a chase. Then there's some lovely underscore that's slightly reminiscent of Horner's Star Trek work. A quick introduction of some slightly comic writing, then more menace, then a settling down.

The "End Credits" don't just reprise the cues you've heard but start really strong with some different ideas alternating with familiar pieces.

One of the themes heard a few times in the score was also given lyrics and made into a song, "If We Hold on Together", performed here by none other than Diana Ross, who sounds great, as usual!
