Where did hard core techno come from?
Techno is commonly said to originate in 1980's Detroit. This
style and period of techno is commonly referred to as Detroit
techno. As hinted at, this "genre" is very much alive. But some
people say that techno has its real origins in the late disco/early
house scene sparked off by Donna Summer's 1977 hit "I Feel Loved"
which at the time was said to be a very "futuristic" song. But
without a doubt, the Detroit techno scene was most likely spawned
by the late '70's early 80's house scene. Noted Detroit techno
artists from the mid 1980's are Juan Atkins, Kevin Saunderson, and
Derrick May.
I hope this answers your question!
