The single ”Boom”, excluding the B-side ”Soldier’s Story”, was Royce’s potential foot in the door in the at-the-time mainstream scene with heavy success following behind it, released on December 14, 1999. It topped at number three on the Billboard Hot Rap Songs charts, gained Royce some recognition in the underground rap scene, was on his debut album Rock City, and led to future frequent collaborations between him and DJ Premier (the producer of this song), leading to the formation PRhyme, years later. This is one of the tracks on Rock City and also one of the most notable from Royce to be produced by Premier, the other being “My Friend”.

The song is explaining how Royce’s lyricism can spontaneously combust like a bomb to the listener.
