But the uncomfortable weather didn’t stifle crowd attendance and enthusiasm for the fiery performances coming from the stages at the music, culinary, humor, and art festival.
Other popular acts were Dave Matthews Band, Black Eyed Peas, Switchfoot, OneRepublic, Bryan Adams and Squeeze.
Sunday’s musical acts include Mumford & Sons, Duran Duran, Sheryl Crow, the Revivalists and Colbie Caillat.
During Cheat Codes’ opening song, Trevor Dahl jumped off the stage an onto a metal barricade in front of the crowd. To the fans’ delight, he threw a fistful of dollar bills skyward at the Del Mar Fairgrounds’ Grandview stage.
Fans reached in hopes of acquiring the concert souvenirs.
He wasn’t the only artist to get up-close-and personal. Earlier in the afternoon, at the opposite stage, Jon Foreman of San Diego-based Switchfoot was literally supported by fans as he waded into the crowd of thousands at the Sunset Cliffs stage.
In the fourth song, Foreman went deep into the crowd by the soundboard and again waded into the crowd as he sang.
In another visually explosive move, OneRepublic lead singer Ryan Tedder performed a high-flying jump from band equipment to the stage during their third song.
In a second day of heat, fans tried to keep cool by downing their favorite beverages — including lots of beer and cocktails. And slipping into the cooled exhibit hall featuring art.
More than three dozen artists at Bing Crosby Hall displayed an extensive variety of work, including paintings, multimedia and jewelry.
Outside, nine artists using scaffolding put their finishing touches on murals, such as Caia Koopman, who painted a climate-change mural on the west side of Bing Crosby Hall.
Meanwhile, cooking demonstrations went on and audiences were entertained by Comedians Tom Green, Jimmy O. Yang, Tig Notaro, and Bert Kreischer drew laughs in the late hours.
The Humor Me lineup for Sunday is Taylor Tomlinson and Ken Kirkman, Bob Saget and Wayne Brady.
