I love the Bajooie Kazooie egypt-inspired level and music
Peter Pringle is a musician who plays reconstructions of ancient instruments, with song texts in ancient languages: link to youtube
He also wrote the theme song for Pringles crisps. This may not be true.
Maybe check out some Arabian Oud desert music? Also, the band Light in Babylon.
Interesting, do we have the slightest idea what their music sounded like? Did they even have music?
They absolutely had music, which we know both by paintings showing people playing instruments and also the instruments themselves which survived as grave goods etc. We roughly know what these instruments sounded like but what we don’t have is any surviving melodies, as they didn’t use written musical notation. We really have very few melodies from before the middle ages, a short but IMO very nice melody with text from Ancient Greece, which was found on a tombstone and some religious hymns from bronze age mesopotamia which was found with notations on cuneiform tablets.
