The set up for the Aftershock music festival in Discovery Park this weekend is nearly complete.
Temperatures are expected hit triple digits Saturday and upper 90's on Sunday, which is a far cry from last year's beautiful, 75-degree opening day.
"We hire a physician called a rock-doc.' He specializes in festival medicine," event promoter Danny Hayes said.
With 19,000 people expected to show up on Saturday, and again on Sunday, promoters had to think quickly and make a decision after hearing temperatures would be so high.
Eighteen misters were purchased, along with fans for the rockers, are being installed to cool people off. Business owners setting up, are doing the same thing.
"We have some little misters, and then we have lots of water," SS7 Body Wear owner Rob Coty said.
Water won't be given out for free but it will be available for sale.
"If this is your genre, this is the show worth getting on a plane and coming to Cac for," Visitors Bureau spokesperson Mike Testa said.
This is the third consecutive year the Aftershock Festival has come to Sacramento, and the Testa says rock fans are expected to spend $800,000 in the city over the weekend.
The festival lineup is also bigger this year. It still has a heavy metal focus with bands like Mastodon, Rob Zombie and Black Label Society, but there is a healthy dose of punk rock with Bad Religion, The Offspring and Rise Against, alternative with bands like Weezer and AWOLNATION and even 90’s nostalgia with Limp Bizkit headlining one of the stages.
