In what is undoubtedly a historic artifact, a letter from über producer Steve Albini to a young and green Nirvana has surfaced. The letter, clearly written before their highly publicized spat following the release of In Utero, details Albini’s recording and engineering philosophy, preferred gear, and even strategies on how to record the new “celebrities.” What’s his preferred drum sound? How does he expect to be compensated (like a “plumber” apparently)? Find out in the unmissable letter below.
