Tommy Victor from Prong shares vocals with Soulfly frontman Max Cavalera
on this track. Cavalera explained to Altsounds.com
how the collaboration came about: "Tommy was on tour with me. I met Tommy in 1994 when I opened for Pantera. Sepultura and Prong both opened for Pantera. I met Tommy again last year when Prong opened for Soulfly and I invited to come sing on the new album and he was very happy to. I told him 'I wrote a song especially for you, it has kind of a Prong vibe to it I hope you like it' and he did, and we came up with the words for 'Lethal Injection' and it was cool."
