As monikers go, Anni B Sweet is the perfect description of the dainty, acoustic-driven work of Spain's Ana López Rodríguez. Her 2009 debut Start, Restart, Undo—and the lilting waltz of sparsely-composed songs like “La La La”—drew comparisons to nu-folk's Regina Spektor. Her breezy pop structures were a success on her cover of a-ha's “Take on Me” before her production style grew to encompass a larger wall of sound. Oh, Monsters!, released in 2012, wraps breathy vocals around angelic organs, while 2015's Chasing Illusions indulges in disco glitz with rushing electric guitars and daunting synths.
