Killswitch Engage frontman Howard Jones has left the band's current US headlining tour. The only reason being cited thus far is "unforeseen circumstances" and All That Remains vocalist Phil Labonte is replacing Howard on the current dates.
A full statement from the band reads:
"Killswitch Engage vocalist Howard Jones is leaving the band's current headlining tour with The Devil Wears Prada and Dark Tranquility due to unforeseen circumstances. All That Remains vocalist Phil Labonte will be filling in for Jones for a few shows in the interim, until the KsE guys can determine what the plan will be for the remaining tour dates, which are currently scheduled to run through the end of March."
