One of, if not the world's biggest techno bash, is Movement, attracting music fans from around the country and the world.
"It's an awesome, Movement it's an awesome scene and just a really cool place to be," said Jacob Shecter.
"You just see everybody come out of their holes come out and celebrate it's beautiful to see," said Josh Colton.
The oddly arrayed and scantily clad packed Hart Plaza drew people of every hue from near and far from the young to the more seasoned.
"We're down here with the kids and what not it takes 10 years off me," said Reggie Hayes.
Even police felt compelled to move. A couple videos were submitted from Movement-goers of police officers dancing to the groove.
"It was crazy. I liked it, he just started doing his thing," said witness Sam Catrambone. "It was fun."
FOX 2: "On a scale of one to 10?"
Catrambone: "Like an eight, maybe."
FOX 2 heard officer Mays has the talent but like other cops who we approached, he was coy.
"At the same time I've got to try to keep it professional," Mays said. "Know when to do it when not to do it."
FOX 2: "And when not to do it is when cameras are around?"
"Yes it is, it is," Mays said. "I've got to refer you to my supervisor."
"It's a great community event," said Officer Stephen Heid. "We're out here making sure everybody's having safe fun. And so far, so good."
Local DJ's also got their chance to shine and it's only fitting - Detroit is to techno as the Bronx is to hip-hop and Nashville to Country music.
"Techno started in Detroit and evolved all over the world," said DJ Raybone Jones. "You got people from Dubai from Rome, Italy Germany Brussels Vancouver."
All paying homage to the city that birthed a genre.
