"It was only four tracks on the machine," Jamaican music legend Lee "Scratch" Perry once said of an early mixing board, "but I was picking up 20 from the extraterrestrial squad."

Last Sunday at the Tokyo club Yellow, the fit 68-year-old Perry burst onto the stage wearing a gilded crown encrusted with faux gems, flashing lights and, apparently, an intergalactic tractor beam through which he channeled inspired madness from his squad in the Beyond.

"CHILDREN!" he shouts in his weirdly shrill voice.
