EAST RUTHERFORD, N.J. (AP) — New York City radio station Hot 97 celebrated its 20th annual Summer Jam concert with young rappers who are dominating the charts, a respected veteran hip-hop group and a slew of surprises.

Lil Wayne, Rick Ross, Nicki Minaj, Mariah Carey and Lil' Kim were among the guest stars of Sunday's show at the MetLife Stadium. Kendrick Lamar, 2 Chainz, A$AP Rocky and French Montana performed sets that electrified the excited crowd. Wu-Tang Clan hit the stage and were solid, though the energy of the audience — filled with a good number of twentysomethings — dwindled throughout their set.

Chris Brown, Miguel, Wale, Fabolous and Joe Budden also performed at Summer Jam XX, where Bone Thugs-N-Harmony, J. Cole and Meek Mill made special appearances.
