“Warning” was released along with “Big Poppa” as the second single from Ready To Die as a double A-side with “Who Shot Ya?” on the B-side. Similar to “Gimme the Loot,” Biggie raps from a dual perspective as he portrays himself having a phone conversation with his associate Pop who is attempting to warn him about a potential plot against him.

In a Ready To Die retrospective for XXL, producer Easy Mo Bee revealed that he originally made the beat for fellow Brooklyn rapper Big Daddy Kane as he felt the Isaac Hayes “Walk On By” sample fit Kane’s style but Kane passed on it and Puff Daddy gladly accepted the track a few months later.
