They might look like diversity poster kids-Russian-born/British-raised DJ Vadim, Brazilian/Chilean (but Swedish-raised) vocalist Yarah Bravo and American rapper Blu Rum 13-but One Self delivers. Vadim brings his considerable skill, as on the solid instrumental "SD2," which feels an atlas in a musical blender. Blu‘s growled raps over the nervous strings of "Paranoid" convey the mood almost too well. But the standout is Yarah on "Over Expose," a song about music-world hoochies-the sweetness of her voice contrasts beautifully with lyrics like "tits, ass, all over the TV screen."Children of Possibility contains a subtle balance of thoughtfulness and playfulness.
