The interesting thing about her is that she's the anthropomorphisation of the 60's dream, trying to situate itself in the 70's and 80's.
'Dreams' was written at Sly Stone's house and in the 70's she encapsulated that empty, lethargic junkie decadence that the hippy dream morphed into. Her bitterness. Her raspiness makes her sound disillusioned and worn from experience.
The 80's then sees her find a new cultural relevance. Luke talked about the 80's being so mournful, because of aids and also because of the end of a more pure humanity. She then finds herself presenting a more innocent vision of herself. Using the lushness of 80's production to show us this dream, hippy world. But there's something cold and off about it. A virtual reality, holographic projection of and idealised past. A translucent paradise trying to cover a cruel dystopia.
