The Vaccines singer Justin Young says he is "petrified" of hurting his voice again, after experiencing problems with his vocal cords.
The musician has had to have operations in the past to repair damage.
"I did have a few issues but I think it's OK at the moment," he told Newsbeat reporter Chi Chi Izundu. "I haven't had any problems recently."
Justin was speaking at Radio 1's Big Weekend, where the band performed to thousands of fans.
"I'm absolutely petrified so I warm up and warm down every day now," he added.
