PHILADELPHIA (CBS) – The Roots Picnic is underway this weekend here at Festival Pier.

Stacie George, with Live Nation, says it gets bigger every year.

“This is in its fifth year. This year, we expanded it to two days. When it started, it was one day; we only did about 3,000 people. Now we’re going to do about 10,000 people between the two days,” George says.

Fans say they come out to the festival for the music:

“I think that more local talent is what’s making it bigger every year.”

“It was opportunity to see a lot of artists that I wanted to see, and then get to see some younger up and coming people as well.”

George says booking the show takes months of preparation.

“We usually start around January. You reach out to every agency in the music business, asking them what is available. And we get a wish list from The Roots, and we just start there piecing together different artists that potentially want to play.”
