Tens of thousands of people are expected to attend what organizers call the biggest event in Bridgeport's history, The Sound on Sound Festival.

The two day concert is being held at Seaside Park.

Over than 20 bands will perform on two stages, but one at a time.

Stevie Nicks and The Lumineers are headlining Saturday's festivities. Dave Matthews and Tim Reynolds are set to play on Sunday.

"This is just part of the renaissance of Bridgeport,” said Bridgeport Music Festivals co-owner Howard Saffan. “It's just an amazing day.”

Organizers say Founder Entertainment, which is putting on the big show, takes pride in producing high-end performances on par with the world's biggest venues.

Sound on Sound is the first major musical festival at Seaside Park since "Gathering of the Vibes" in 2015.
