Custom-made instruments are the key to scoring for composers Anže Rozman, Kara Talve and musician Russell Emanuel.

Emanuel is a co-founder of the composer collective Bleeding Fingers Music along with Hans Zimmer and Steven Kofsky. Among the shows they’ve worked on that could grab voters’ attention are Apple TV’s “Prehistoric Planet.”

In the show’s prior season, they created custom instruments made from fossils, bones and dinosaur skull replicas and married them to a standard orchestra to create an otherworldly soundscape.

For the third season, “Ice Age,” Talve and Rozman wanted to bring audiences into more familiar territory, especially since humans were evolving and existing at that time. “The score is slightly off, but it’s much more emotional,” Rozman says.

The first episode, “The Big Freeze,” features a woolly mammoth giving birth in the blizzard. Talve explains that one discussion was about how to show the scale of the animals and highlight it through music.
