"An over-sugared combo of Katy and big names in grime, techno, hip-hop and d'n'b ... this marriage between bleeding-edge production and Katy's lightweight-but-likeable vocals works best when her collaborators aren't afraid to stay true to their original sounds. The trippy synths of 'Honey' and 'Heavy' - produced by Kaytranada and Mr Mitch respectively - help to lift otherwise forgettable songwriting, while 'Calm Down', Katy's much discussed team-up with Four Tet and Floating Points, is a brilliant slice of weirdo disco".
