A "serious throat condition" sustained by leader singer David Draiman has forced Disturbed to cancel their upcoming tour dates in support of 'Asylum.' Concert promoter Live Nation posted the news. Details are scarce, but the condition was not specified.

While the condition is not permanent, the singer must cease performing for at least four weeks in order to fully and appropriately heal. Refunds are available to all ticket holders at the point of purchase.

Disturbed's label said that no further statement was forthcoming. Noisecreep wishes Draiman a speedy recovery. He will be back rocking in no time at all.
