After their debut in the early 2000s, Finnish five-piece PMMP surfed a wave of glossy ‘80s revivalism—juddering synths, rock guitars and the twin vocals of Paula Vesala and Mira Luoti injecting melody into tested pop tropes. Beneath this lustre lay a heart of passionate activism: the band acted as vocal supporters of Amnesty International's work to combat violence against women and human rights—a political message sweetened by their unerring grasp of vintage electro-pop. It's an intoxicating combination—with a string of platinum albums attesting to their irresistible brew.
