[sdiy] Essential listening?

[synth at charlielamm.com]

If someone asked me what the essential CDs and albums are for
blues guitar, I could answer with a bit of confidence (eg: Robert Johnson
"King of the Delta Blues"; Muddy Waters "The Chess Box Set"; etc
etc etc.

However, I am not well versed on essential CD's for synthesizer.  Since
I am building these now, maybe I'd better get up to speed.  Can anyone
offer his or her opinions?

There are obviously no right or wrong answers.  My goal is to get ideas
for doing recordings and demos and what not.

What I am looking for is an synthesizer-based recordings, as opposed to
bands that have a few synthesizer solos on their albums or whatever.
EG:

Wendy Carlos "Switched on Bach"
Jean Michelle Jarre "Oxygene"

I am sure the list goes on and on....can anyone help out?

Thanks!
