Killswitch Engage will reunite with absentee singer Howard Jones for a string of US dates next month.Jones, who left the band for undisclosed "personal reasons" in February, was replaced with All That Remains frontman Phil Labonte and former KsE vocalist Jesse Leach."It became overwhelmingly obvious to all of us around Howard that he is in no condition to be on tour right now and that he needed to get off the road and get himself better," said the band in an official statement at the time. "It's a personal matter and while we understand everyone's curiosity and concern for Howard and the band, we appreciate everyone respecting Howard's privacy at this time." Jones' first gig back will be on May 19 in Norfolk, Virginia on May 19.
