At a Guardian debate last week, a bitter old soul complained about the moral decline in today’s youth. I feel like ripping their old gizzards out, these old moralists. I wish she had been at the Dome in Brighton tonight, where three bands and dozens of dancers showed what a feisty and talented bunch they really are. Guided by the brilliant choreographer Hofesh Schechter, the dancers exploded into action to blistering rock beats and swept across the stage in wave after wave. It was absolutely thrilling. Hofesh just unleashed the energy of these teenagers and they flew. They had no problem in blasting out to a venue of this size. It was loud, raw and accomplished.
