20. Chloe X Halle, 'Sugar Symphony' EP
Teenage sisters Chloe and Halle Bailey made something sweet out of pop's biggest co-sign. The Beyoncé protégées prove they have an ear as unique as the woman who signed them on Sugar Symphony, their debut EP and a potent collection of soulful R&B that fuses pop and indie rock to skin-tingling perfection. Single "Drop" makes use of their haunting harmonies and pairs them with the type of expansive synth-bass combinations that made releases from another sister act – the Knowles sisters – such staggering achievements. Meanwhile, a song like "Lazy Love" highlights the bubblegum pop sensibilities and exceptional minds of these two emerging talents. B.S.
