This is a cover of a Sonic Youth song, “The Diamond Sea”, which can be found on their 1995 album Washing Machine.
The original is a nineteen-minute noisefest (with the unedited version running about 26 minutes), and you can listen to it right here:

Time takes its crazy toll
And how does your mirror grow
You better watch yourself when you jump into it
'Cause the mirror's gonna steal your soul
I wonder how it came to be my friend
That someone just like you has come again
You'll never, never know how close you came
Until you fall in love with the diamond rain
Throw all his trash away
Look out he's here to stay
Your mirror's gonna crack when he breaks into it
And you'll never never be the same
Look into his eyes and you can see
Why all the little kids are dressed in dreams
I wonder how he's gonna make it back
When he sees that you just know it's make-belief
Blood crystallized as sand
And now I hope you'll understand
You reflected into his looking glass soul
And now the mirror is your only friend
Look into his eyes and you will see
That men are not alone on the diamond sea
Sail into the heart of the lonely storm
And tell her that you'll love her eternally
Diamond Sea was written by Kim Gordon & Steve Shelley & Lee Ranaldo & Thurston Moore.
Yeah Yeah Yeahs released Diamond Sea on Sun Jan 01 2006.
