The Hangout Music Festival revealed the lineup for this year’s event today, and it’s looking pretty good. The Black Keys, The Killers, OutKast, Jack Johnson, Queens of the Stone Age, Pretty Lights, The Avett Brothers, Modest Mouse, The Flaming Lips and many more will take stage on the beautiful white-sand beaches of Gulf Shores, AL May 16-18. In anticipation of the festival, we’ve compiled some reasons why you should check out five of the must-see acts that will perform.

For a more comprehensive look at the Hangout line, make sure to check out our in-depth look at the artists that will be appearing there.

OutKast

The Southern hip-hop icons have finally reunited after too many years out of the spotlight, making them the most anticipated act on this year’s festival circuit. Additionally, OutKast have not released any new material since 2006, so fans can expect to hear plenty of their favorite classics. Big Boi has also been killing it with his past few solo tours, and there’s no telling how much they’ll step up the production for these reunion shows. On top of all that, OutKast should have worked through all the rust of their first few gig by mid-May, making the Hangout Music Festival a perfect time to check them out.

The Black Keys

OutKast aren’t the only highly anticipated duo at this year’s Hangout Music Festival. The Black Keys are also on the the bill, and there’s no doubt that they’ll be bringing a hard rock edge to the beach during this year’s event. Their stellar 2011 performance at the festival took place before the release of their smash-hit album El Camino, so fans can expect to hear a few more tunes from that LP when they take the stage this year. The pair have also been working on the follow up to that album for some time, and there’s always a chance they’ll treat festivalgoers to some fresh material.

Moon Taxi

We’re happy to shed some light on Moon Taxi, who are shaping up to be this year’s dark horse performance. These guys have been on the rise for some time and 2014 is set to be a breakout for them. The Nashville indie-rockers (emphasis on the “rock”) just made their second appearance on the Late Show with David Letterman, and if there’s any justice in this world, their set at Hangout will be one more big step on their rise to stardom. Rock n’ roll fans would be foolish to miss them.

Portugal. The Man

Portugal. The Man haven’t performed at Hangout since 2011, and they’ve released two solid album’s since then. Their latest release, the Danger Mouse-produced Evil Friends, was one of our favorite albums of last year, and we’re psyched to see them deliver it live. Their effortless combination of rock sensibilities and pop hooks make them accessible to fans from across the musical spectrum. These guys also hail from the frigid land of Wasilla, Alaska, so they should be enjoying the Summer sun and ocean breeze a much as anyone.

Trombone Shorty & Orleans Avenue

Few bands know how to throw a party like Trombone Shorty & Orleans Avenue, but that’s no surprise given their New Orleans origins. Led by the show-stopping Troy “Trombone Shorty” Andrews, the group have developed their sound and style through years of heavy touring. All this time on the road has made consummate professionals out of the young band, and it shows on stage. In addition, Trombone Shorty & Orleans Avenue are also coming off a fantastic new album–2013’s Say That to Say This–that showcases their abilities in the R&B arena, as well as the funky brass-rock that we’ve all come to know and love.
