Even Bruce Springsteenisn't too big for a cameo. The Bossjoined musiciansZach Bryanand Caleb Followill of the Kings of Leon for a rendition of his 1982 classic "Atlantic City" at Bryan's July 20 MetLife Stadium show in New Jersey. The Kings of Leon and Jersey-based Rock band Front Bottoms were the openers for the concert, whileSpringsteen, 75, was a surprise guest, joining later for a quick-lick guitar solo on Bryan's track "Revival" during the encore. "Proud to call him my hero, one of the greatest songwriters to ever live," Bryan said before introducing the legendary rocker. "If you guys will have him, this is Bruce Springsteen!" Why Bruce Springsteen changedhis set list to end concerts with this song The pair then moved on to play "Atlantic City," a harmonica-heavy ballad offSpringsteen's1982 album "Nebraska." Followill, Bryan and Springsteen stood at side-by-side mics, passing the lyrics back and forth, before embracing at the end of the track as the crowd coo-ed "Bruuuucee!" Bryan, 29, has followed in Springsteen's singer-songwriter footsteps, often folding angst into his scratchy, smoker's vocals and genre-bending music, which features a cocktail of folk, country and soul. Bruce Springsteen and the E Street Bandstill rock, quake and shake after 50 years Springsteen joined Bryan on stage last year in Brooklyn and Philadelphia, lending old-school rocker legitimacy to an emerging act. The two also collaborated on the track "Sandpaper" off Bryan's 2024 album, "The Great American Bar Scene." The July 20 show was the third for Bryan this weekend at MetLife, the first time a country artist played three nights in a single stand at the venue. Springsteen is fresh off the release of a previously unheard cache of tracks from years passed.
