I haven't come across one with a full orchestral score, but the Jim Weiss narration is incredibly theatrical. It's a single narrator, but he does distinct voices for every single character—Mowgli, Bagheera, Kaa, the lot. His pacing and the way he uses his voice create a really dramatic effect that feels almost like a one-man play. He might use some light musical motifs, but it's not a full cast with a separate score. For pure storytelling skill, though, it's top-tier. Sometimes a brilliant solo performance can be more immersive than a crowded cast, in my opinion.
