On this day, Jan. 26, in hip-hop history…

2014: Kendrick Lamar teamed up with rock band Imagine Dragons for a mash-up performance of the two parties' current hits; "m.A.A.d city" for Kendrick and "Radioactive" for Dragons, at the 56th Annual Grammy Awards. It's been considered by many to be a performance so epic, that it deserves some new-millennium preservation.

Those of us lucky enough to see hip-hop history in the making during that particular televised Grammy show, or even better, see it live, will remember a stage-commanding K.Dot leading the explosive show. With both Lamar and the band members dressed in white, TDE's frontman rapped a mile-a-minute while colored powder cannons went off around him and the rockers.

Between the blended bass lines and the raw energy exhibited by Kendrick and Imagine Dragons lead singer Dan Reynolds, the mash-up was undoubtedly one of the best, and most tweeted, performances of the night. The collab was released on iTunes the next day under the title, "Radioactive (Remix)" and helped boost album sales of both artists post-show.

A week after this electrifying show, Imagine Dragons performed the remix for a second time on Saturday Night Live, where Lamar would reprise his role as mesmerizing rap genius once more.

Kendrick also had somewhat of a rocky experience on this night back in 2014. He went home without any awards, and most notably, his critically-acclaimed major label debut good kid, m.A.A.d city lost Best Rap Album to Macklemore and Ryan Lewis' The Heist. The Compton superstar took it all in stride, and sat down with XXL to discuss how he felt about the loss. "He went out there and hustled and grinded," he said. "Everything happens for a reason; the universe comes back around, that's how it go."
