Cassidy, a producer from California, according to LA Times, wore a shiny blue suit, a beige hat and square sunglasses when he welcomed the crowd to the DNC's roll call as "We Are Family" by Sister Sledge played.

"Now, we're going to pass the mic from state to state so that all our voices are heard all around the nation," said Cassidy.

Tennessee delegates jammed out to Dolly Parton's "9 to 5" while Texas took it to the floor with Houston-native Beyoncé's "Texas Hold 'Em."

New York Gov. Kathy Hochul bragged about the Empire State's historical significance over Jay Z and Alicia Keys' "Empire State Of Mind." California Gov. Gavin Newsom later praised the Golden State over a mashup of Tupac Shakur's "California Love" and Kendrick Lamar's "Not Like Us."

Another Beyoncé song, "Freedom," played as Harris made another surprise appearance, accepting the party's nomination in a live broadcast from a campaign event she and running mate Tim Walz were attending in Wisconsin.

'Truly surreal'

Cassidy took a not "normally fun or cool" political event, as described by former White House Press Secretary Jen Psaki, and turned it into something grand, with fun music and dancing.

"The whole night was truly surreal," Cassidy told Psaki in an MSNBC interview.

The four weeks of "meticulous" planning went into setting up the DNC roll call.

The ceremonial roll call of the delegates happened on Tuesday, the second day of the Chicago convention.

Before this year, music had never been a part of a convention's roll call, said Cassidy. And that's a fact he "really had to wrap his mind around."

Who is DJ Cassidy?

DJ Cassidy is no stranger to political events or the Democratic party.

The DJ, who got his start playing at school functions, was called on when former President Barack Obama "needed a maestro," they called him to play at both of the president's inaugurations, his 50th birthday, and former First Lady Michelle Obama’s 50th birthday at the White House, according to Cassidy's website.

He's also played at events orchestrated by Oprah Winfrey, Jennifer Lopez, Naomi Campbell, the Kardashians and even performed at Jay-Z and Beyonce's wedding.

How did DJ Cassidy get his start?

The DJ fell in love with music at a young age. On his 10th birthday, "DJ Cassidy was born" when he asked his parents to get him two turntables and a mixer.

"His love of music and appreciation of sounds both classic and cutting-edge date back to age five when he discovered pivotal Hip Hop records like Run DMC's "Sucker MC's" and cult classic dance films like ​​'Breakin,​'" states his website.

Every weekend, Cassidy would visit record stores, study vinyl sleeves and learn who wrote and produced his favorites.

The young DJ studied artists from across genres and vowed to play all kinds of music for people all over the world.

"DJ Cassidy’s career is the culmination of a lifetime of deejaying around the world, observing people react, and making people move," stated his website.
