Jay Z stood with Democratic nominee Hillary Clinton inside Cleveland’s Wolstein Center on Friday night for a free concert.

The event, scheduled to begin at 8 p.m., was delayed after a police "situation" around 6:30 p.m. which shut down a portion of the Wolstein Center.

Entrance to the event was limited before the incident concluded.

The rally was complete with surprise artists J Cole, Big Sean and Chance The Rapper. The greatest surprise came from Queen Bee herself, Beyoncé.

Beyoncé performed with her husband Jay-Z before Hillary Clinton was welcomed on stage.

The event drew thousands of supporters, packing the Wolstein Center nearly to the brim.

Free tickets were given out last weekend near the Cuyahoga County Board of Elections and one of Clinton’s campaign offices.

Spokespeople with Clinton’s campaign confirm the event was a blatant attempt to rally support amongst voters who may not be traditionally political.

Clinton volunteers were given preferred access in the front section, to encourage people to be more involved in campaigns and engagement.

Other star acts have been used in an effort to increase the vote overall.

Katy Perry will be deployed by the Clinton campaign to Pennsylvania outside Philadelphia in voter turnout efforts.

Pharrell was in North Carolina on Thursday for Clinton.

Jennifer Lopez and Marc Anthony were in Florida.

Sunday, Clinton will be joined in Cleveland by Cavaliers star LeBron James at a rally at Public Auditorium at 4:30 p.m. Doors will open at 1:30 p.m.

James endorsed Clinton for president in an op-ed piece last month.

African-American early voting is reportedly lagging behind 2012 levels in states including Ohio, North Carolina and Florida.

Ohio eliminated a week of early voting where voters could both register and vote at the same time.

But there are two weekends of early voting compared to one weekend last year.

To win Ohio, Clinton needs a big margin in Cuyahoga County. That translates to a strong turnout in African-American voters who traditionally back Democrats.
