After undergoing several kidney surgeries, American Idol winner Phillip Phillips will make his comeback performance on July 4 on the lawn of the U.S. Capitol, The Associated Press reports.

For the annual Independence Day celebration, Phillips will sing before an expected crowd of 300,000 people. It will be the 21-year-old's first time at the nation's capital.

Most recently, Phillips underwent another surgery in early June to remove kidney stones that were too large to pass.

"I'm getting better each day, so that's a good thing. I'm just walking around, getting my strength back together," he said. "It was tough, you know, those first few days, but I'm getting to where I can pick the guitar back up and write a little bit."

When Phillips takes the stage on July 4, he'll join Matthew Broderick, Megan Hilty, U.S. Olympic athletes and other celebrities at the concert. It is set to broadcast live on PBS and NPR.
