I'll stretch the time period out to 1982-1989. The seeds of Blue Monday seemed to be sown in 1982 with Temptation-5 8 6 and some other tunes. PCL is amazing, Thieves Like Us and Lonesome Tonight in '84 are stunning bridges to Low-Life, Low-Life is amazing, then they get sideswiped by a big rig and end up in a ditch which explains the State of the Nation/Shellshock nightmare, but they right themselves with BLT, and good songs if not great production with Brotherhood, Touched, True Faith, 1963 and a mostly truly superior rerecoring of Temptation in '87, followed by Technique which was the pinnacle. I've started to listen to the old albums again and damn is Technique good. Just an amazing, amazing album. After that they imploded which is a massive bummer because like others I think we may have missed a potentially great album in late '87 if they'd not done the Salvation pap, and if they'd managed to hold it together and maybe perform a Brian Wilson (not tour, and just do an album) following Technique in '91.
Alas at least the band survived and while few have been totally happily with their work post-Technique there still have been some astonishingly good tunes: Regret, Special, At Close Range, Here to Stay, WFTSC, Turn etc.
