Great lost lps...the 80s....synth pop and others..

While not synth pop, the first two Fleshtones lps, "Roman Gods" and "Hexbreaker" are very enjoyable "retro with a fresh twist" efforts. I'm happy to have held on to these hard to find gems.

Oh goodness, how could I forget Japan and Spandau Ballet?

Gary Newmans Pleasure principle, awesome synths !!!!!

From left field, Men Without Hats-Rythm of Youth. Most would likely consider this crap and I guess it has a digital character but the sound is dynamic and fun.

Great calls re Close Lobsters, Kraftwerk "Computer World" and "Tin Drum"

Not really "lost" but some of my favourites include:

The Blue Nile - A Walk Across the Rooftops (1983)
New Order - Power, Corruption & Lies (1983) (in fact anything by New Order)
Buggles - The Age of Plastic (1980)
John Foxx -The Garden (1981)
Orchestral Manoeuvres in the Dark - Dazzle Ships (1983)
Orchestral Manoeuvres in the Dark - Architecture & Morality (1981)
The Associates - Sulk (1982)
Tears for Fears - The Hurting (1983)
The Human League - Dare! (1981)
Scritti Politti - Cupid & Psyche 85 (1985)

Not heard (vinyl is quite hard to find) but will one day:
Alain Bashung - Novice (1989)

Not 1980's but in the spirit and fantastic:
Junior Boys - Last Exit (2004)
