Here's something interesting from nme.com:
"NIRVANA have been given the approval of US academics by being put in a special archive to be preserved for future generations. The grunge trio’s seminal ‘Nevermind’ joins works by The Beach Boys, Public Enemy and James Brown in the US Library Of Congress’ vault. According to the BBC, the 50 recordings have been deemed 'culturally, historically or aethestically significant.' ...Other material includes The Beach Boys’ ‘Pet Sounds’, the Star Wars soundtrack and spoken word recordings of Neil Armstrong’s moon landing...."
Neil Armstrong is by far my favorite spoken-word artist. Much better than Henry Rollings.
