Once again Dave Grohl is proving that he’s a musician’s musician, by writing a letter to a young garage band’s local town council. The guys in the band Black Leaves Of Envy from Cornwall, England were told that their garage rehearsals were making too much noise, and they were asked to cut it out. So after three months of no practice, they reached out to our good old buddy Dave Grohl and asked for his help. He promptly responded by writing this letter to the town council, and also posting a DIY garage soundproofing article. What a guy!!
