Rapper Cardi B was among the well-heeled performers at Jay-Z‘s star-studded TIDAL X: Brooklyn Benefit Concert at Barclays Center in Brooklyn, NY on Tuesday, October 17.

People are still buzzing about the 6 hour concert where top tier superstars like Jennifer Lopez, center, shared the stage with unknowns and up-and-coming artists. At age 48, J-Lo put the younger performers to shame.

Performers included Chris Brown, pictured, Stevie Wonder, T.I., Remy Ma, Cardi B, DJ Khaled, Iggy Azalea, Willow Smith, Jadakiss, Yo Gotti, A$AP Ferg, Fifth Harmony, Mack Wilds, Fabolous, Fat Joe, Swizz Beatz, Daddy Yankee, and many more.

Remy Ma, pictured above, also performed. Proceeds from the concert will go toward disaster relief efforts in the U.S. Virgin Islands and Puerto Rico — after Jay-Z and organizers take their cut.

Jay-Z’s wife, Beyonce, was also in the house looking pretty. But she’s still recovering from tummy tuck surgery, so she did not perform.
