The SF Giants had a home game against the L.A. Dodgers last night and while fans were entering AT&T Park they were surprised with a flashmob dance performance. Did you catch it?

The flashmob was in promotion of the upcoming movie (opening July 27) Step Up Revolution. Now, a true flashmob wouldn’t have a corporate entity behind it promoting something and it wouldn’t have people holding signs up, but the dancers (including local hip-hop dancers B-Boys and one of the stars of Step Up Revolution tWitch) were still pretty tight and on-lookers were definitely taken by surprise.

Here’s a video shot by one of the bystanders (@dmaniar227):
