Sunday's attendance of 19,000 beat Saturday's record-breaking tally, bringing the final count to 36,000 for LouFest's 2014 edition. The sun was out in full force in Forest Park's Central Field this time, though there were some oases of shade for concertgoers to escape to. Music Times checked out sets from The Districts, Portugal. The Man, Moon Taxi, Trombone Shorty & Orleans Avenue, Lettuce, Grouplove, Matt & Kim, and OutKast.

Andre 3000 and Big Boi, collectively known as OutKast, finished off the 2014 edition of LouFest with a 90-minute set, 24-song set. They opened with "B.O.B." and tore through a long list of hits including "Ms. Jackson," "The Way You Move," "Players Ball," and "So Fresh, So Clean." For "Hey Ya!" they brought a group of women on stage to "shake it like a Polaroid picture" and joked about their fathers hopefully not being in the crowd. The closed the set with "The Whole World."

Andre 3000 used his black jumpsuit, on which he has been writing messages, to address the unrest in Ferguson, a suburb of St. Louis. It read, "Can one rest in peace & violence." Big Boi also nodded to the conflict by holding up his arms in a "Hands Up, Don't Shoot" stance with a bandana around his mouth.

One of the rowdiest acts of the day, Matt & Kim threw a massive party at the Forest Park Stage. As usual, the duo ran around the stage, hyping up the crowd. At one point, Kim even jumped up on her drum set. They played favorites including "Cameras," "Let's Go," "Overexposed," "Block After Block," and "Lessons Learned." They also took a stab at a cover of R. Kelly's "Ignition (Remix)."

Grouplove took the Bud Light Stage Sunday evening as a night of dancing awaited concertgoers. They kept the energy high through favorites such as "I'm With You," "Lovely Cup," "Ways To Go," "Colours," and their breakout hit "Tongue Tied." The band also tried its hand at a cover of Beyoncé and Jay Z's "Drunk In Love" and ended the set with a cover of The Who's "Baba O'Riley," joined by members of Portugal. The Man.

Lettuce brought the groove to The Shade Stage Sunday afternoon and had even the most preppy of festivalgoers dancing. About five songs in, the Boston funk veterans were joined onstage by vocalist Alecia Chakour, whose voice sounded like a blend of James Brown, Amy Winehouse and Janis Joplin.

Trombone Shorty entered the stage with a bang and got the Bud Light stage grooving at the height of Sunday afternoon. He visited songs from his latest album, Say That To This, as well as older favorites. However, it was his cover of Green Day's "Brain Stew" that really got everyone partying.

The Nashville space-pop group brought a heavy dose of sugary tunes to The Shade Stage.

Alaskan rockers Portugal. The Man opened with a cover of Pink Floyd's "Another Brick in the Wall, Pt. 2," setting the stage for a solid set as usual. They ran through "Purple, Yellow, Red and Blue," "All Your Light (Time Like These)," "Atomic Man," "Modern Jesus," and "Creep in a T-Shirt" as well as a cover of "Dayman," adapted from the FX sitcom It's Always Sunny In Philadelphia. From there, they went into "So American," "People Say" and a cover of Oasis' "Don't Look Back in Anger."

The Philadelphia-based band played their first St. Louis set since having their van and gear stolen last time they were here. But they didn't seem to hold a grudge (or if they did, they channeled it into their music) and delivered an impressive, passionate set that included songs of their latest EP.
