Saturday’s Sweetlife Festival was as much about the music for fans as it was about face-painting, food-truck tastings and unusual photo ops.

In its second year at Merriweather Post Pavilion, the festival created by the founders of Sweetgreen featured two stages and 20 scheduled performers, with D.J.’s keeping the music flowing in between each band performance.

D.C.’s food trucks, including The Big Cheese, Jose Andres’ new truck Pepe, a Shake Shack tent and Pleasant Pops, parked along the festival’s back perimeter. Fans flocked the trucks, forming long lines for food and tents for beer and mixed drinks.

Fun., an indie pop-rock band that sold out its two upcoming performances at the 9:30 Club, took to the main stage to start the show. The crowd was subdued during their performance, the first to hit the stage, singing softly until the band began playing its hit single “We Are Young,” prompting singing, dancing and shouting.

The afternoon brought an energetic performance by the group LP and a more mellow set from The Shins. As the sun set, rain fell, forcing concert-goers to seek cover under the massive pavilion with many pushing to get into the pit to see the next act, Kid Cudi.

The rapper played old crowd favorites from his debut 2009 album “Man on the Moon: The End of Day” including “Soundtrack 2 My Life,” “Pursuit of Happiness” and “Up, Up and Away.”

Fans took advantage of a lengthy intermission to push into the main stage center pit. Swedish DJ Avicii took the stage with colorful flashing lights and a giant turntable set-up as flashes of smoke added a palpable excitement to his more than hour-long set.
