Finland's Irina Saari released a handful of singles before taking off with the theme song for an acclaimed TV drama. The song, which soundtracked Juulian Totuudet, was a mid-tempo electronic pop piece that balanced the singer's sweet fragility and powerful dynamism. Her 2004 debut Vahva was the first of three albums to go Top 10, with a five-piece band further boosting her sound with loud, energetic guitars. When these quiet down, Irina's pained, crystalline vocals shine. Floating over evocative keys, or dancing sensually along a symphony of accordion and brass, she's always enrapturing.
