“You’re all that I want,” Makthaverskan’s Maja Milner sings with audible ache on “Vienna,” setting a yearning tone for the Swedish dream-pop band’s third album. But if Milner is consumed by despair, her band is drunk on adrenaline. On III, broken hearts are soothed by vapor-trailed guitar jangle and pulse-pounding rhythms that whip past in a blur, pushing anthems like “In My Dreams” to blissful peaks while infecting comedown ballads like “To Say It as It Is” with a sense of ecstatic restlessness.
