I hope DR. Schulze at the age of 68 and Vangelis @ 72 are doing OK.
These three were the pioneers of electronic music.
IMO you should add a few others in there! Kraftwerk- Autobaun early 70's, Emerson, Lake, & Palmer- Picture of an Exhibition, they pulled that off live which was quite a feat considering the primitive synth of the day, 71ish. Gary Numan was doing electonic stuff late 70'.
Then there was unknowns starting out like Yanni, David Arkenstone, Neuromium, Jean Michel Jarre, Michael Garrison, Redshift, Ian Boddy, Ron Boots, Kitaro.
