The artwork most commonly associated with the song is from a competition the band held for the then upcoming album The Battle of Los Angeles. Competing artists were given titles to put on their covers including "Agunzagun", "Battle Hymns" and of course, "The Battle of Los Angeles". One of the titles was even a verse from "Calm Like A Bomb" - "The Riot Be The Rhyme Of The Unheard".Tom Morello eventually used the name "Battle Hymns" for a track on his debut album, One Man Revolution in 2007.
"Calm Like A Bomb" is notable as a display of guitaristTom Morello's creative use of a whammy pedal. Like many of RATM's songs, the song's lyrics discuss social inequalities. The song also features a reference to Emiliano Zapata. Tim Commerford uses a combination of a home-made overdrive pedal and the Jim Dunlop 105Q Bass Wah pedal on his bass throughout the song. In Rolling Stone magazine's feature article this past year on the new "Guitar Heroes," a section was printed about Tom Morello, and Calm Like a Bomb was cited as the prime example of his skill and fame on the guitar. He has occasionally referred to the extremely high whammy-pedal effects used in songs such as this as "pterodactyl sounds."
"Calm Like A Bomb" made its live debut on June 11, 1999, at the K-Rock Dysfunctional Family Picnic in Wantagh, New York at Jones Beach Amphitheater.
