It is also the band's last single recorded with their bassist Chi Cheng before his serious automobile crash in the following year and before his death in 2013.

In a later interview on Reddit, Tankian was asked how the collaboration had come about, replying: "Chino asked and I obliged :) We´ve all been friends and toured together for many years" [2] Calling the song an "industrial banger with swooshy space-rock overlays," Rolling Stone writer Christian Hoard favorably compared Chino Moreno's vocal style to that of Thom Yorke.

Directed by Bernard Gourley, the video depicted hip hop influences and breakdancers, while the band performed on top of a parking structure with the Los Angeles skyline in the background.
