The Icelandic superstar Bjork's new album UTOPIA (released Nov 2017) includes Sarah Hopkins' music for Harmonic Whirlies on a co-written track titled FEATURES CREATURES. Bjork wrote to Sarah in July 2017 letting her know that she'd created a melody that matched Sarah's music Kindred Spirits for Harmonic Whirlies & that she'd like to include it on her upcoming album.
Since then Bjork has been using Sarah's Harmonic Whirlies in her live shows & her album UTOPIA was nominated for a Grammy Award for 'Best Alternative Music Album'.
