In 2006, Irwansyah crossed over into music with "My Heart", a duet with Acha Septriasa for the Heart movie soundtrack. Its lush romantic pop created a new career path for the Jakarta-born actor: stripped-down balladry, buttressed by his expressive voice. Subsequently, Irwansayah has stretched that template in surprising ways, working with the Indopop innovator Melly Goeslaw and crafting songs like "Camelia", a robust slice of blues rock, and "Selalu Untuk Selamanya", a guitar-inflected number that reveals his gift for tasteful yet confident musical emotions.
