A lot of Led Zeppelin fans worship Jimmy Page and regard him as a deity. On the other hand there are a great many people who think he is the devil incarnate. They are both wrong of course. Page was an excellent and very reliable session musician in the 1960s and subsequently joined The Yardbirds alongside Jeff Beck after Eric Clapton had departed. It is not mentioned in his Wiki entry but he knew that he needed to learn music notation which would help his songwriting, and so that is what he did but it also helped him to write music that has lasted to this day and a lot of his music lends itself very well to orchestration.
A lot of classical musicians could see how the songs were structured and how they could be transcribed for large or small ensembles. This is a selection from the many available on YouTube. I have included two versions of Kashmir to show how the same tune can be interpreted in very different ways; the first by Ghislaine Valdivia being very dramatic and rhythmic and the second being more lyrical.
Good music is always a nourishment for the soul!
