Living legend Dave Grohl once again reinforced his position as the nicest man in rock yesterday as he came to the aid of a group of noise-restricted Cornwall musicians.

After complaints to the their local council, teenage four-piece Black Leaves Of Envy were forced to keep noise levels at their garage rehearsals down to between 30 and 40 decibels - which, as Grohl notes, is "approximately the level of a dishwasher at 15 metres distance".

The band reached out to Grohl - who once said bands should get into their garages and start practising if they want to be the new Nirvana - and incredibly, the Foo Fighters frontman responded, writing a well-considered letter to Cornwall Council, detailing the benefits of dropping the restriction and encouraging the arts. You can read the full letter below.

Clearly on a roll, Grohl also penned a surprisingly detailed blog on effective soundproofing and sound treatment, which you can read on Foo Fighters' website.

The Foos may not be breaking up, but who knows: perhaps Dave would be well-suited to a sideline in UK local government policy.
