Some good 80s stuff: the great neoprog albums such as IQ's Lush Attic and The Wake, Fish-era Marillion, Geoff Mann-era Twelfth Night, Pallas's 'Sentinel'.
Also, the birth of metal prog in the last 80s (Fates Warning, Dream Theater's debut album).
On the avantgarde side of prog, Continental bands such as Art Zoyd and Univers Zero, and Scandinavian such as Von Zamla did some amazing, weird stuff, while in the early 80s Tangerine Dream managed to incorporate digital synths into their (still) well accomplished compositions.
Last, but not least, the Japanese prog gave birth to great bands such as the Canteruryesque Ain Soph, the Camelesque Bellaphon, the RtF-esque Kenso, and the Crimsonian Bi Kyo Ran.
Not that bad, actually... Regards.
