When Backstreet Boys opened Into the Millennium in July 2025, they were the first pop act to headline Sphere. The run was meant to be short. It has since played to more than 750,000 people across 47 sold-out shows, and this winter they are back for a second straight New Year's Eve inside the dome, plus a Grand Prix weekend show and a post-Christmas run.
Backstreet Boys: Into the Millennium at Sphere
Backstreet Boys at Sphere is built around Millennium, the 1999 album that went diamond and gave the world I Want It That Way. The show treats the dome as a spaceship: a countdown, a blastoff, and a sequence in which the five of them fly over the crowd. After the album, the set runs through the rest of the catalog, Everybody (Backstreet's Back), The Call and As Long As You Love Me among them.

Where: Sphere, behind The Venetian, east of the Strip. When: seven shows, November 21, 2026 to January 2, 2027. Run time: about 90 to 100 minutes. Best for: anyone who was 13 in 1999, and the friends they dragged along then.
The countdown or Christmas week
New Year's Eve is the night this winter is built around: the show starts later than usual, putting midnight inside the dome. The post-Christmas shows fit a holiday trip, and the November show falls on Formula 1 Grand Prix weekend, when hotel rates on the Strip run highest.
Inside the dome
The set opens with Larger Than Life, It's Gotta Be You and As Long As You Love Me, and the music is locked to the visuals, so it barely changes night to night. There is no encore break. Fans have made white outfits an unofficial dress code, and the BSB Terminal fan experience at The Venetian runs alongside the residency for anyone who wants photos and memorabilia before the show. This is the band's second Vegas residency, after Larger Than Life at Planet Hollywood from 2017 to 2019.
