From the Open Culture web site:
Sometime in the summer of 2016, this isolated track of Grace Slick’s vocals for White Rabbit--probably the most famous Jefferson Airplane song and definitely one of the top ten psychedelic songs of the late ‘60s--popped up YouTube.
I've loved the song for all its decades but have never heard Slick's haunting vocals isolated. If you're familiar enough with the song (and who isn't) you'll begin to mentally insert the instruments, resist that temptation.
She has an extraordinary voice and you owe it to yourself to spend a few minutes in audio bliss.
