The first three or four OMD albums were great, the next three OK and then everything went downhill. For Architecture & Morality alone they'd be up there. Mary Margaret O'Hara's one-hit-wonder, Miss America, is similarly worth a top ten slot. Her concert at the Dominion in London in 1989 (I think) was one of the best gigs I ever saw. And I loved 1000 Mexicans: several sublime singles, one album and some great gigs, all mid-80s. I championed them a bit in Sounds but despite/because of this they split soon after.
Always had a bit of a soft spot for Mike Oldfield, especially Ommadawn and Incantations and remember seeing him at Wembley Arena while I was still at school. Rubbish last three decades though. Anything released on Egg and featuring Richard Pinhas was bound to be good and Ose's Adonia ('78) scored on both counts.
The Orb and Orbital both qualify. To be honest I got a bit bored of them after a while but the early stuff was genuinely innovative. Oval took electronica into glitch territory - their Diskont album was excellent. And finally, respect to German composer/pianist Hans Otte (who died in 2007) - his Book of Sounds is pretty essential - and O Yuki Conjugate who recently celebrated their 25th anniversary. Happy birthday Andrew.
