The gathering aimed to "reclaim" the community's popular Oregon District, which was the site of the shooting on August 4 that resulted in nine deaths and many injuries.
"And we're not just doing this for our city", he added.
The likes of Stevie Wonder and Chance the Rapper were among performers at Dave Chappelle's Dayton, Ohio gig Sunday thrown to honour the victims and those affected by the recent mass shooting. The event also happened to fall on the same weekend as Dave Chappelle's birthday.
The artist Thundercat was first to take the stage in what's expected to be a star-studded affair that will stretch into Sunday night.
The concert, which was held at RiverScape Metropark, was attended by about 20,000 people.
"Dayton, Ohio - no matter what's going on, no matter how tough times get, we hold our heads high", Chappelle told the huge crowd gathered in the Oregon District, where the shooting took place.
Tickets were free for the event. No more will be available, the event page said.
The event boasted performances, dining, drinks, and opportunities for people to donate to local organizations assisting businesses with recovery.
"We're still here and we're still strong".
"Locally there's a determination to not let that define us", he said.
