Khaled's new album, Liberté, could not be more aptly named. Casting off the shackles of record company formatting, the Rai king has freed that extraordinary voice from beneath layers of synthesisers. Khaled digs deep into the past on his new album, bringing a handful of his old songs to light including the wonderful Raïkoum. But the outstanding feature of this new album is the reinstatement of the "intro", a scene-setting prelude on which the singer's carefully modulated voice extrapolates on the theme of each song.
