The Magic Numbers Capitol Music   ••• Sound   •••

Is it the sound of the Strokes hitting the sandbox or Belle & Sebastian getting a swift kick of punk angst? Or the Mamas and the Papas for the 21st century? In any case, the Magic Numbers — a London foursome of two sets of brothers and sisters — perform jittery pop that's tastefully sweetened with 1960s AM-radio harmonies. The opening cuts on their self-titled debut have an optimistic bounce — and stay tuned for the second half, where reflective odes point to the band's versatility.
