Kendrick Lamar will take the biggest stage in music Sunday after his notorious beef with Drake. Here's how we got here.

Drake’s second diss track used artificial intelligence technology to include verses from Tupac and Snoop Dogg, two of Lamar’s influences. In his own verse, Drake accuses Lamar of delaying his response track because of the imminent release of Taylor Swift ‘s “The Tortured Poets Department.” (Lamar collaborated with Swift on “Bad Blood.”)
