Krewella has become known as EDM's fiercest girl group, dropping battle cries over the heaviest of bass. The signature sound of sisters Jahan and Yasmine Yousaf is one part pop-punk swagger, one part emo lyrics and a whole artillery of machine sounds—dubstep, drum 'n' bass and electro-house. These are mosh-pit rave-rock anthems suited and booted for the youth of today.
