Apple TV has released the soundtrack for "Prehistoric Planet: Ice Age", featuring new music composed by Hans Zimmer alongside Kara Talve and Anže Rozman of Bleeding Fingers Music, performed by the BBC National Orchestra of Wales. The release continues the trio's long-running collaboration on the "Prehistoric Planet" series and coincides with their Emmy nomination for Outstanding Music Composition For A Documentary/Nonfiction Or Reality Program.

For the Ice Age instalment, the composers moved away from the bone- and fossil-based instruments used in earlier seasons to depict the Mesozoic Era, instead incorporating ancient and custom instruments such as a replica Divje Babe flute (based on a Paleolithic artefact found in Slovenia in 1995) and a giant 12-foot Octobass capable of producing subsonic 16 Hz frequencies to evoke woolly mammoths. High flutes, violins and brass were stripped back to create a darker, heavier orchestral palette, while a new instrument called the Triceratone was developed to replicate the guttural call of an extinct terror bird species.
