Killswitch Engage announced in 2012 that they had parted ways with singer Howard Jones and would be welcoming back Jesse Leach, their original vocalist. Guitarist Adam Dutkiewicz
remained friends with Jones after he left the band, and through him the past and present Killswitch singers got to know one another.
It was Leach who suggested that the two frontmen should unite for this Atonement
track. Dutkiewicz told HMV.com
: "I think it's a good message to show fans that there are no hard feelings and no dramas with this band."
