This year, about 300,000 people packed Chicago's Grant Park for Lollapalooza. The lineup was bigger than ever and catered to a crowd of all ages, reports CBS News correspondent Adriana Diaz.
For fans, the three-day festival met all expectations: long days of music, little room to dance, the requisite and retro flower crowns.
But what was once an adolescent rite of passage is trending younger than ever. The married-with-children set is opting to bring their kids along.
Eleana and Bradley Keding from Detroit are festival fans from their teens. This is the first time the couple in their 40s brought their twin boys.
"Once you start seeing live music and you love it, it just continues and so we wanted to pass it on to these kids," Elena said.
The parents said they would have had to leave the boys at home if not for Kidzapalooza.
"It's almost like this little hidden garden," Bradley said. "They can kind of just play like a playground with music and then you can take them out and actually experience a big show."
Jane's Addiction frontman Perry Farrell started Lollapalooza 24 years ago. As his own kids grew up and fans started having kids of their own, he added Kidzapalooza to include them all.
"I wanted a place that they could have fun at and learn and enjoy themselves and bring their friends and that's what they do," Farrell said. "It's not a Disney thing; it's a cool 'Lolla' thing and I think its really cool to have that."
Kidzapalooza's performers included the Jimmy's and the Helmets, a band of middle-schoolers with 11-year-old Tye Trujillo on bass.
His dad Robert Trujillo of Metallica was part of Lollapalooza's headline act.
"It's great because they're sort of opening the day and we're closing the day," Trujillo said.
Tye said when he grows up he wants to be a bass player like his dad.
Trujillo hopes festivals become more and more kid-friendly.
"The Kidzapalooza stage is a great fun atmosphere. Rock music needs to keep going. I'm glad that it's happening through the Kidzapalooza stage," he said.
Like the bigger festival, the Kidzapalooza experience went beyond the stage. There were drum circles. Karaoke. Even rock and roll stylists on hand.
