Just noticed an interesting segment in this magazine.
Glitterglaze Glacier (the ice world) is said to twinkle in sync with the music. I love when music and their worlds interweave. E.g. the enemies in New Super Mario Bros. that stop on the beat.
The music to Glitterglaze is also said to be very sombre and beautiful; Andy reckons it's one of the best pieces Grant has ever written. Andy goes on to say that the music is quite different to Banjo-Kazooie's and is an example of Yooka-Laylee doing its own thing instead of trying to perfectly emulate Banjo-Kaxooie's tone.
