This is "Woodstock Al #6," a strange and fascinating DIY cassette of covers by an unidentified artist. In 2000, a fellow named Jim Fletcher sent the cassette to legendary WFMU personality and music historian Irwin Chusid. From Mei Clover who posted the audio to YouTube for posterity:

This is a tape filled with strange, distorded guitar noodling, barely audible vocals, out-of-rhythym drums, and songs just barely recognisable to what they're supposed to be. You've never heard something like this before. The identity of Woodstock Al is unknown, and the tapes Woodstock Al 1-5 are still lost. Because these tracks are just barely recognisable, here is the track list.

1. Communication Breakdown 2. Purple Haze 3. Sunshine Of Your Love 4. Light My Fire 5. Manic Depression 6. Hello, I Love You 7. Cocaine 8. One Way Out 9. Every Day I Have The Blues 10. I Don't Live Today 11. You Got Me Floatin' 12. Paranoid 13. Sweet Child 'O Mine

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.
