Illness has forced the cancellation of Diana Krall’s autumn tour and pushed back the release of Wallflower, which had been scheduled for October, to February 2015. The Canadian jazz singer has suffered from complications brought on by a case of pneumonia, her condition, according to a statement, becoming “much more chronic than first anticipated.” Krall is unable to travel or engage in any promotional or touring activities for at least another 6-8 weeks.
