The Black Leaves of Envy, a four-piece band from Praa Sands consisting of Cerys Plenty, 17, Dylan Plenty, 15, Adam Jones, 17 and Lewis Cunningham, 15, reached out to Grohl after a series of complaints were made about the noise levels emanating from their rehearsal space in a suburban residential area, reported Contactmusic.
Introducing himself in the open letter as "David, an American musician of over 30 years", his appeal read: "For musicians that lack the resources to rehearse in professional facilities, a garage or basement is the only place they have to develop their talent and passion.
"The preservation of such is paramount to the future of art and music. Without them, where would we be? As a proud father of three aspiring musicians myself, I have always made this a priority in our home, to great results."
Adam Jones, of the band, reacted to the letter, saying: "It's just been surreal - I'm speechless, seeing the Foo Fighters tag you in a post on Facebook was just incredible."
A response from the council came soon afterwards, acknowledging the point but saying they were duty bound to investigate noise complaints.
