In the mid-1990s, a 7th grader named Tom Clark gifted his buddy a cassette containing his cover of Nirvana's then-new album Nevermind. All of it. A cappella. In 2008, the recipient released the cassette to the world. Above is Tom Clark's "Nevermind" and the story is below:
so i got a little story for you. early to mid nineties. i am in 7th grade. art class. you know how you really get to know the other 3 or 5 people at yr table. you become friends. well, this young gent and i had a passion for a little underground band-then known as nirvana.
at some point i lent this lad a random mixtape i had lying around. it probably had bad rock music on it. he lost the tape...
to repay me...FOR SOME REASON HE THOUGHT THAT HE WOULD MAKE ME A TAPE OF HIMSELF SINGING THE ENTIRE ALBUM 'NEVERMIND' BY NIRVANA---a cappella STYLE!!!
...recorded in a karoake machine...complete with puberty-filled voice cracking and occasional incorrect lyrics. pause and record style editing.
