Alicia Keystook to The Tonight Show stage with a full roster of seismic talent, bringing up film score great Hans Zimmer and TDE's prodigal son Kendrick Lamar to perform their Pharrell produced contribution to the Spiderman 2 OST "Its On Again." K dot sat at the foot of the stage to open the song with his furious verse, disappearing as Keys' refrain came and opened the door for Hans and his miniature string section to take over the poppy nu-disco flame. Also taking the stage was The Smiths' six-stringer Johnny Marr and the breathing beat machine araabMUZIK to help fill things out in the absence of P and that other late-night outfit The Roots. Watch the star-strudded ensemble perform "Its On Again" below.
