Summer Jam 2015 is in the books, but that doesn't mean you can't relive all the action once again.

The 22nd edition of Hot 97′s Summer Jam got underway at Met Life Stadium in East Rutherford, N.J., Sunday, June 7, and the parking lot to the arena was jam packed with hip-hop elite. As the premiere hip-hop concert of the season, Summer Jam has always been known for its surprise guests. And this year was no exception.

Joey Bada$$ seemed to bring all of Brooklyn with him for his afternoon set, and Travi$ Scott nearly incited a riot as the Festival Stage headliner. Chris Brown brought on G-Unit in all their glory for his Main Stage set, although it was reported Fif and his clique had some trouble getting in at first. For Fabolous' set on the Main Stage, Loso seemed to bring out every rapper he knew within a 20 mile radius. Fab "and Friends" consisted of French Montana, Busta Rhymes, Method Man, Redman, Raekwon, Lil Kim, Mobb Deep, Ma$e, Remy Ma, Fat Joe, Black Rob, and The LOX.

Big Sean commanded the stage solo for his nighttime time slot, showing he didn't need Kanye or Drake for assistance while Kendrick Lamar definitely surprised fans when he chose to bring out internet sensation Welven da Great as his special guest.

For Meek Mill's show closing set, he called on none other than his "baby," Nicki Minaj. After giving a quick rendition of some of her harder-hitting tracks like "Only," Minaj saunters off stage, but not before making her love for Meek publicly known. Omeeka lives on!

Here's a rundown of the best backstage pics and performances that made the night as legendary as Summer Jams past.
