Jaylen Brown said farewell to Boston on Sunday in an event organized by his brand, 741 performance, and others, and highlighted by the state of Massachusetts presenting Brown with a key to the city. The Philadelphia 76ers acquired Brown in a blockbuster trade on July 1, ending the forward's 10-year tenure with the Celtics. Brown made his mark on the court, helping the Celtics win the 2024 NBA Finals and earning Finals MVP honors. He also made a strong impact in the community.

His brand on Aug. 7 announced the "741 Frequency Fest" at Boston Common, with the city and the local restaurant Hue Boston among the organizers. Sunday's event was held from 2 to 7 p.m. ET. It was free to everyone, and tickets were not required. Fans took advantage, flocking to show their love for one of Boston's own. They signed a thank-you board with messages such as "you will truly be missed" and "Boston will always love you."

Later on in the event, Boston Mayor Michelle Wu went on stage and shared that she had attended with her government colleagues because "Jaylen has been about so much more than basketball here in Boston." Wu explained that she has seen Brown in Boston schools, classrooms and parks. "He has changed lives throughout Boston. That's why there are so many people here," Wu said.

On behalf of the state of Massachusetts, Rep. Christopher Worrell of Boston gave Brown a key to the city "for his incredible work in the Black and brown community." Brown put his hands over his head in stunned fashion. He posted on X after the event, writing, "God is crazy." Brown, wearing his Celtics championship ring, broadcasted live on Twitch during the event for almost 2½ hours.
