Record crowds turned out to attend our parent (deliberate pun) festival, Lollapalooza – which sold out for all three days, meaning an estimated 225,000 people inhabited the space at Grant Park in Chicago this weekend – and Kidzapalooza also saw it’s largest crowd to date today, due to the impromptu performance by Lollapalooza founder, Perry Farrell and the rock legend that is Slash (photos and a video clip below).

But they weren’t the only highlights for Kidzapalooza Day 3. Other special guests included John Butler (of the John Butler Trio) who was joined by his daughter on stage, Peter DiStefano playing his guitar with a violin bow (!) and a return performance by the Paul Green School of Rock All Stars, who were described as playing “one of the loudest sets all weekend” (USA Today).

The Kidzapalooza stage rocked all day with additional performances by Q Brothers, Homemade Jamz’ Blues Band, The Jimmies and G. Love & Special Sauce. And the activities were once again a huge hit.

“(My daughter) came back and said, ‘I silk-screened, I dyed my hair, and I got a tattoo,’” said Mates of State singer, Kori Gardner, a mother of two. “I was like, ‘Well, you’ve been to Lollapalooza.”(USA Today)
