No Use for a Name frontman Tony Sly is dead, the band's label announced.
The musician was 41. His cause of death has not yet been disclosed.
"It was with great sorrow that we must say goodbye to Tony Sly of No Use For A Name," the band's longtime label, Fat Wreck Chords, wrote in a posted statement. "We received a call earlier today of his passing, and are devastated. We have lost an incredible talent, friend, and father - one of the true greats."
"One of my dearest friends and favorite song writers has gone way too soon," label head "Fat Mike" Burkett added. "Tony, you will be greatly missed."
In June, Sly did an interview with Spinner discussing time he'd spent in the hospital prior to the band's NXNE performance.
"It's a herniated disc on my cervical spine. I'm in pain all the time and that sucks," he said. "I've been getting epidural shots, seeing a chiropractor and I'm in physical therapy."
He also looked back at the band's "wild" past, saying the group had grown up over their two-decade-plus career.
"I realized at one time, that I was drinking at every single show. I mean, regular people don't do that," he said, explaining the band had become more "civilized." "Your liver can't take that much alcohol for that many years."
Sly joined the veteran punk act in 1989, two years after the San Jose, Calif., group's formation. He lead the band through a number of albums, including 1995's "Leche Con Carne" and 2008's "The Feel Good Record of the Year," the group's most recent effort.
He also embraced mellower sounds on several releases outside of the band, including a pair of acoustic solo albums.
