Kendrick Lamar's trophy shelf isn't any more crowded after Sunday's Grammy Awards, but the emcee is still making waves for his outstanding performance. Compton's "good kid" took the stage alongside rockers Imagine Dragons to perform both Kendrick's "m.A.A.d. City" and Imagine Dragons' "Radioactive."
The performance rocked the crowd and even got country star Taylor Swift out of her front row seat and moving with the song's beat. As the performance hit TV screens across the nation, it also became one of the top trending topics on Twitter.
