Avenged Sevenfold have canceled their remaining U.S. tour dates due to lead "singer" M. Shadows' recent vocal ailments. Shadows has since been diagnosed with vocal fatigue and ordered to rest his voice before A7X is forced to tour as a Tom Waits tribute band.

The rejuvenated M. Shadows and Avenged Sevenfold will return to action in Japan on October 15. Look for the band to return to America in November with Buckcherry and Shinedown.

Below is the video of M. Shadows performing at Avenged Sevenfold's last North American gig in Huntington, West Virginia, just before he was sidelined by doctors.
