Heavy bass and attitude might allow for some comparisons, but in thinking of Robyn and Kelis on the All Hearts Tour, let the comparisons stop there. At the 9:30 Club last night, preceded by Far East Movement and Dan Black, Kelis came with a husky alto, a sparkling silver wig, and spiked heels. Robyn had her own shock of white hair, sneakers and a slightly sweet soprano. To address a sold-out club of full of adoring fans, the ladies asked for nothing but some hands in the air and some reckless dance moves — and receive they most certainly did.
