If you’ve ever seen the Foo Fighters, you may have noticed that Dave Grohl is always, ALWAYS chewing gum. I’ve met the man dozens of times and every single time, he’s chomping on some gum. Same time ever time I’ve seen the Foos play live.
It’s a health thing, actually. Hear me out.
Dave sings with a lot of enthusiasm and punctuates a lot of songs with big screamy parts. Chewing gum, he says, keeps his mouth and throat lubricated, thereby making it (a) easier to scream and (b) keep him from doing some real damage on his vocal cords.
At last check, Dave says the best gum for the job is Dentyne Ice. Glad I could help.
