Kate Boy is an electropop quartet from Sweden. "Kate" is the Australian Kate Akhurst, "Boy" is the trio of Swedish producers Rocket Boy (Markus Dextegen, Oskar Sikow Engström and Hampus Nordgren Hemlin). They have an interesting sound, inspired by The Knife, Deep Cuts-era. Less weird than The Knife and definitely more listenable than Shaking the Habitual.

They made 3 videos so far (the only songs officially released so far):

PS: The programming of their beats is really impressive in my opinion.
