We were part of this whole cultural exchange program between Earth and Ksistisk. The trip was short, it’s not that far. They were great hosts, built a special mobile hotel suite and an enclosed stage for us, both with their own artificial Earth normal atmosphere.
The thing was, Ksistisk hearing is all high-frequency, so our music would have been largely lost on them. They decided to send the main mix through a pitch shifter, putting it through the Ksistisk’s PA system transposed two octaves up.
Weird thing is, after a while some of our songs actually sounded better that way.
