For many years, Jay-Z closed out his concerts with “Encore,” a soothing, triumphant number from “The Black Album,” which at the time of its release in 2003 was billed as something of a retirement. “From Marcy to Madison Square,” he rapped, sketching an arc that had taken him from a Brooklyn housing project to headlining the most symbolically important arena in the country.


That used to be enough, goal-wise, but no musician has reframed the potential for bucket-list completion and brand extension like Jay-Z, who in the last decade has consistently sought new ceilings to break through. That journey brought him to the Barclays Center in Brooklyn on Friday night, for the first show of a sold-out eight-night run in this new rusty bunker that will house the Brooklyn Nets, a team that he owns a small piece of, and for which he is the unofficial ambassador.


All he needed was a song to tell the tale, and early in the night, after offering a bit of the back story of how he came to be involved with the team and its arena — “What’s up Bruce?” he said, referring to the developer of Atlantic Yards, Bruce C. Ratner — he rapped a bit of a new song, boasting, “They call me Eight Shows H-O/You can stunt like that when you own the whole place, though,” then going on to link the dark street mythology of his past to the improbable executive mythology of his present: “Shooters on my team/ No, really, I got shooters on my team.” (Jay-Z owns one- fifteenth of one percent of the Nets.)


Even though this was a night filled with tremendous symbolism, in which a son of the rough end of Brooklyn took his place at the peak of the borough’s revival, it was almost subdued.


“I’ve been on bigger stages. I’ve been all around the world. Nothing feels like tonight,” Jay-Z said, adding later, “I’m really overwhelmed by the moment.”


In 2010 he shared a headlining bill with Eminem in Yankee Stadium, but Friday’s show did not try to match that night’s explosive energy. In February Jay-Z headlined Carnegie Hall, but this show did not have that one’s knowing class frisson. Instead, this was an ultraminimalist affair.


For almost two hours, Jay-Z was essentially alone on stage; his band played on risers jutting out from the 45-degree-angle wall behind him. Wearing a custom black No. 4 Brooklyn Nets jersey that read CARTER, his last name, he drew upon almost two decades of Brooklyn-friendly anthems, songs that long been hits, but had still been waiting for a home-borough debut of this scale.


He opened with the sinister “Where I’m From” and the exuberant “Brooklyn (Go Hard)” and got to “Empire State of Mind,” which was his first No. 1 hit on the Billboard pop chart. Elsewhere, he tweaked some of his lyrics to note the occasion: “New York’s ambassador” in “What More Can I Say?” became “Brooklyn ambassador,” and on “Do It Again (Put Ya Hands Up),” he changed the lyric about a blue Yankees cap to one about a black Nets cap.


The Marcy projects where he grew up were “15 minutes away,” he noted. “I’m from murder murder Marcyville,” he rapped on “Murda Murda,” before telling the crowd, “Sometimes it’s gonna get real dark in here tonight.”


That was an exaggeration, of course. There was palpable energy in the room throughout the night. Before the show, people gathered outside the arena as lasers of blue light shot out from atop the building.


There was a heavy but not overbearing police presence on the surrounding streets. At the very end of the show, Jay-Z showed off some of the cynicism that sticks with people who grew up on the wrong side of power, urging the crowd to be peaceful on its way out. “You know they waiting for us to” make a mistake, he said, using rougher language.


He emphasized meaning over popularity, though often the two went hand in hand. He happily lingered over songs from his 1996 debut album “Reasonable Doubt” and sped through plenty of better-known ones. The spare setup did a good job of highlighting the dexterous wordplay that sometimes gets obscured by his success. Late in the night, he did his verses from “Clique” and “3 Kings,” two recent hits that served as a reminder that he is not just capturing past glories, but still also making new ones.


Mostly, though, he was repaying a debt to the borough. During the encore, he brought out the night’s only guest, Big Daddy Kane, the Brooklyn rap legend from the late 1980s to early 1990s, whom Jay-Z would sometimes perform with early in his career. For his short set of classics, Mr. Kane was joined by his longtime backup dancers Scoob Lover and Scrap Lover for old routines that were endearing for their slight creakiness.


Jay-Z also did not wait long before acknowledging the Notorious B.I.G., who was killed in 1997, a superstar who still had pinnacles yet to reach. Jay-Z led the crowd in rapping his hits “Kick in the Door” and “Juicy,” pausing for emphasis on that song’s celebratory boast: “Spread love, it’s the Brooklyn way.”


And that is what he did, over the course of the night mentioning specific addresses he had lived at — 560 State Street, 534 Flushing Avenue — and insisting he was not any “different than anyone in here tonight.”


That was the unexpected charm of the show, which was but one in a long line of self-coronations for Jay-Z, but which felt like a community gathering. His biggest accomplishment was making something momentous feel utterly normal.
