A teaser clip for Alicia Keys, Kendrick Lamar and Pharrell Williams' video hit the Web on Tuesday.
The 47-second teaser splices movie scenes with music video clips in a very organic way, starting with a shadowy figure walking through what we assume is an Oscorp lab. Pharrell makes a brief appearance, peering through a surveillance system, as film composer Hans Zimmer conducts his orchestra.
There is a brief Spidey cameo as well, but the teaser's true heroes are the musical ones as Kendrick Lamar and Alicia Keys look ready for action. Before the preview closes we see a punk-styled Keys sitting in a chair, lifting her head, ready to sing her song before the whole thing fades to black.
The song, which dropped online in March, starts off with a fearless verse from Kendrick, who took on a crop of rap gladiators last year with his verse on Big Sean's "Control." "And everybody knows the story of David and Goliath/ But this is bigger than triumph/ This is for the warrior/ This is for you and I," he snarls, before Keys brings some calm with her vocals.
