KILLSWITCH ENGAGE: Pro-Shot Footage Of ROCK AM RING Performance

Professionally filmed video footage of KILLSWITCH ENGAGE's June 1 performance at the Rock Am Ring festival in Nürburgring, Germany can be seen below.

KILLSWITCH ENGAGE 's April 22 performance at at the New England Metal & Hardcore Festival marked the band's first concert with singer Jesse Leach in more than nine years.

Leach sang on the band's first self-titled album, which came out in 2000, and on their landmark 2002 Roadrunner debut "Alive Or Just Breathing". Leach left the band in 2002 and was replaced by Howard Jones, but his work on "Alive Or Just Breathing" has always been revered by diehard, longtime KILLSWITCH ENGAGE fans.

"Honestly, we didn't want to jump into anything too quickly," Adam told AOL's Noisecreep in a recent interview. "We were in a position where we could take our time and try out as many singers as we wanted. There are a lot of talented singers out there, and we didn't want to rush everything. We ended up mulling it over a bit, and we tried out a few different people.

"When we got back in the rehearsal room with Jesse, it just felt right. He's one of my good friends, and the awkwardness of meeting someone for the first time, and all of that stuff, was gone when he jammed with us again. We also knew what Jesse is capable of, so it just took all of us getting in a room together again to remember how cool it once was. He blew us away."

Regarding the reasons for Leach's original departure from KILLSWITCH ENGAGE ten years ago and whether those same issues will come into play now, Adam said, "He was feeling a lot of frustration [back in 2002]. He didn't know how to take care of his voice, and he would blow it out every couple of shows. We had to cancel a lot of shows because of that. He was also a newlywed, and they didn't know how tough it would be to be in a relationship when the other person is a road dog. It was a lot of pressure on him. All of those things piled up, and it put him in that bad place. But these days he's really learned how to take care of himself on the road. His marriage is also going great, and they've figured out how to make it work, even though one of them is a touring musician. Jesse's in a much better place now, that's for sure."

KILLSWITCH ENGAGE is hard at work on material for the follow-up to 2009's second self-titled album.

In a recent interview with the "Brock And The Fatguy" radio show, Jesse stated about KILLSWITCH ENGAGE's new material, "I have the 14 demos for the new KILLSWITCH record, and let me tell you, I'm glad that they didn't turn into TIMES OF GRACE [songs], and I'm glad that KILLSWITCH is gonna have the opportunity to write another record with me — or a few more, God willing. I can tell you right now from the demos, the people are gonna be really surprised; they're setting the bar up high once again. I'm literally within day three of just listening to them and just sort of digesting them. It's really fast and it's really heavy. It's not what people are going to anticipate, I'm sure. I literally am getting chills right now talking about it. It's gonna blow the doors off people, man. It's gonna be great."
