Listen to Grace Slick's Hair-Raising Vocals in the Isolated Track for "White Rabbit" (1967) | Open Culture

"Drenched in echo, Slick sings with martial precision, completely in command of her vibrato and dipping and rising all through the Phrygian scale (also known as the Spanish or Gypsy scale.) And no wonder, the song was written in 1965 after an LSD trip at her Marin county home where Slick had listened to Miles Davis’ Sketches of Spain over and over again for 24 hours. Compare the original version to Davis’ track “Solea” to hear what I mean."
