Here are a couple, but I'm sure I'm not scraping the bottom with these:
Kraftwerk - Everything from
Autobahn on is electro-pop. This is for the better or for the worse depending on how big of a Kraut rock purist you are.
Giorgio Moroder -
From Here to Eternity,
E=MC2, and
Knights in White Satin are all worth listening to. Straight up disco fun.
Donna Summer - She's more hit or miss to me. Kinda bland when she misses. Giorgio also produced a bunch of her stuff, so it's pretty similar.

The Age of Plastic is a pretty solid record (with "Video Killed the Radio Star" being the obvious hit single). I'm not such a fan of their second one -
Adventures in Modern Recording. Gary Numan - Another so-called one hit wonder who is worth further investigation. I heard about him on the BBC3 tv show
The Mighty Boosh.
Pete Shelley - Fresh from the Buzzcocks, Shelley released a solid synth-pop record called
Homosapien. This one's generally pretty easy to find for cheap at yr local record store, and worth every penny.
Zapp & Roger Zapp & Roger - AKA Roger Troutman. This guy is THE inspiration for Dr. Dre's
The Chronic. He also did things with the vocoder that are downright obscene, and some 8-10 years before Daft Punk.
Strut records put out a nice Italo disco compilation called
Disco Italia that covers some of the more obscure Italian bands coming relatively late to the disco party during the 80s.
Hope this helps! I'm sure there are plenty that I missed. I would like some new stuff to hunt down as well!
