According to their official web site
, The White Stripes "are unfortunately postponing their upcoming Japanese tour dates because Jack White is suffering from an acute vocal cord problem. As part of his treatment, the doctors have instructed Jack not to speak or sing for the next two weeks." There's no word yet on how White is faring during his doctor-imposed period of silence, though he might want to recall the cautionary tale of Miles Davis
, who famously blasted out his voice in similar circumstances and spoke in a muted rasp for the rest of his days.
