A contingent of Foo Fighters fans are growing concerned for Dave Grohl‘s voice, fearing that he may have done permanent damage to his vocal cords. After the band played last Monday night (June 11th) in Antwerp, Belgium, one fan wrote at the Foos' Reddit page following the show that he was worried about Grohl's voice.

The fan wrote, "I was at the Antwerp gig last night, and I thought the state of Dave’s voice was kind of worrying -- towards the final third it began cutting out entirely (noticeably on 'Breakout')." He added, "I know it’s been an issue since the start of the tour, but it’s clear that it’s not a ‘cold’ any more. And it can’t be any good long-term."

Another fan replied, writing, "I don’t think it’s shot just yet, but he does seem to have "off" days more often . . . It’s a miracle it’s held up this long tbh, given that he’s a smoker who doesn’t seem to take particular care of his voice and screams all night long on a regular basis."

Grohl, who started as a drummer, told us a while back that he was nervous about becoming a frontman with Foo Fighters: "When the Foo Fighters started playing, it was scary, because singing upfront with a guitar in your hand and having everyone stare at you as the lead vocalist is a lot different than just chiming in backup vocals when you're behind the drums. So I was nervous, and actually when recording the first Foo Fighters record, I had never belted it out in the studio before, so I didn't know what my voice sounded like."
