XXL’s Freshmen ’10 Live concert went down last night (March 31) at New York City’s Highline Ballroom.

The show, hosted by DJ Envy of Power 105.1 and sponsored by MTV2 and Corona, was packed from wall to wall with fans waiting to see their favorite freshmen and the headliner for the evening, Cam’ron.

The night started off with a set by Jay Rock. The gruff voiced MC brought along up-and-coming Compton rapper, Kendrick Lamar, to play hype man, as he performed a handful of of his mixtape staples, including the hit single "All My Life."

Next up was Kanye West protege Big Sean, who performed his popular song, "Getcha Some" and a new track called “Fuck You Doin’ (Bullshit),” as well as his “Supa Dupa Lemonade” freestyle. Freddie Gibbs followed, starting off his set list with “Womb to the Tomb,” his collaboration with fellow classmate Pill. The Gary, Indiana rep later brought out Jay Rock to premiere their duet, "Rep to the Fullest." [Watch below]

Pill took the stage next before passing the mic to fellow ATLien Donnis, who wowed the audience with a slew of surprises. Not only did he have a violinist accompanying him, the newly-signed Atlantic rapper boasted cameos from Estelle and Ryan Leslie, who played the keyboards during the Atlanta Brave's rendition of "Gone."

When Nipsey Hussle arrived, his entourage clashed with Rock’s flamed up crew backstage but it was all love. Both crews celebrated unity by shaking hands with one another in the midst of throwing up their hoods. L.A. transplant Gibbs and Neighborhood Nip even took shots of Hennessy with Jay Rock in honor of his birthday. Veteran Doug E. Fresh made a surprise appearance during the show before headliner Cam’ron hopped onstage. The Harlemite arrived around 1 a.m. with an entourage of about 40 members all supporting Killa's latest protege Vado. The young rapper went through his standout cuts, like "Large on the Streets," "Stop it 5" and "Ric Flair," before Killa  jumped into "something a little more familiar." Cam had the crowd in a frenzy as he rocked out to "Down and Out," "Leave Me Alone," "Wet Wipes" and "Get it in Ohio."  —Brooklyne Gipson
