Setelah berpisah dengan vokalis Howard Jones dan mengadakan sejumlah audisi untuk posisi tersebut akhirnya Killswitch Engage telah menetapkan ke siapa posisi tersebut berlabuh. Tentunya bukan Philip Labonte, vokalis All That Remains yang belakangan kencang digosipkan karena hubungan mereka yang dekat. Tepatnya, posisi vokal yang kosong tersebut jatuh kembali kepada Jesse Leach yang nggak lain adalah vokalis dari KSE periode 1999 – 2003 lalu.

Berikut adalah pernyataan resmi dari KSE mengenai perihal ini :

"After much deliberation and careful consideration, we are pleased to announce that Jesse Leach has rejoined Killswitch Engage. Our job was to find the best person to fill Howard’s shoes: a decision based on talent and not familiarity … Truth be told, Jesse blew us away in auditions. The room seemed charged with electricity. He commanded both new and old material, and proved, beyond a shadow of a doubt, that he wanted to do this. The choice became very clear and apparent … This change is very exciting. We know you’re going to love it. This is truly a new era in KsE history and it is ready to shred your face off. So, please help us in welcoming Jesse back into the KsE family; he is a rare and great talent, a fact that older KsE fans have known for years. Here is to a killer new record and a bright future. The five of us cannot wait to write this record and play shows together and bring that feeling to our fans. It’s been far too long.”

Leach also commented on his return, saying “It is a great honor to rejoin my brothers after all of these years. After some discussion and much reflection, it was obvious to me this was the path I was meant to take. We got together and jammed on the ‘Howard-era songs,’ as well as some Alive or Just Breathing-era songs and we all felt the synergy … I look forward to writing the new record, since the demos sound absolutely amazing, as well as breathing new life and getting comfortable with the soulful songs Howard has written. It is a new chapter of my life filled with new and exciting challenges. I will give all that I can to honor the position I have been given and take nothing for granted. I will sing every note with all of my soul. I am very blessed and very thankful to be back in the KsE family! All things happen in their due time and now is the time for this reunion and new direction."
