Kendrick Lamar brought the DAMN. tour to Detroit on Wednesday night (July 26), and while he was performing he brought out a special guest—J. Cole.

Cole came out performing his 4 Your Eyez Only cut "Deja Vu." He'd go on to perform tracks like "No Role Models" and "A Tale of 2 Citiez."

For years, fans have wanted these two to do a whole project together. They were working on one as early as 2011, but they put it on hold once they both really started to blow, and all we've got from them together is "Black Friday." 

Watch the moment K. Dot brought Cole out and the ensuing madness in the clips below.
