Contrasting Diana Ross' and Donna Summer's Careers:

[Boogiedown]

They certainly overlapped but only marginally crossed paths.

They both seemed to be overnight successes, and both were in the care of good hands that propelled their careers. I would say one had to work a lot harder at her positioning in the music scene than the other, and one's candle flickered more briefly although perhaps more sensationally.
Both were in high demand yet both were struggling by the time the 80's took hold and shifted music tastes .
Can't recall what Geffin paid to "get" Donna, not anywhere near what RCA paid out for Diana I wonder the difference?
Both seemed to care more about their personal lives at that time as well.

Other thoughts??
