Staged at Brooklyn’s Barclays Center, *The Millennium Tour Presents: The Boys 4 Life Tour* brings a hip-hop and R&B bill to one of New York City’s largest arenas. The lineup spans eras and scenes, with Boys 4 Life alongside B2K and Bow Wow, plus Waka Flocka Flame and Jeremih, placing early-2000s radio staples beside club-tested rap. For a city that often measures pop memory in live sing-alongs, the event functions as a time capsule with a current pulse. The scale can flatten nuance, but the shared repertoire carries the room.
