Nice collection of bands you got going there. Being a Prog Rock head, I have my respects for Pink Floyd and Radiohead. My musical tastes go for the more Genesis like prog rock, and of course, in the same wave, Marillion, my fav band.

(Others include IQ, Arena, Porcupine Tree and Pendragon).
Anyway, no, King's Quest IX's music will all be a score, completely instrumental except for maybe one or two songs in the game that will be totally original, but, for the most part, it will be instrumental.
Hope that answers the question
