The Veronicas—Australian twin sisters Jessica and Lisa Origliasso—have enjoyed considerable pop success at home and abroad following the release of their 2005 debut. Since then, they've steadily added to a knockout cocktail of rock riffs and electro beats. The duo has expanded its sound with elements of country, soul, and EDM, while their killer pop instincts have attracted keen-eared collaborators like Butch Vig and Daniel Johns. A nonstop stream of fresh ideas continues to fan the flames within these sisters' hard-punching hits.
