the "is joey beltram the father of hard techno" tangent on the "local" thread made me wonder what tracks got people into hard techno...the possibilities are huge, so maybe people limit to 5 or fewer?

...for me those would be:

F.U.S.E. - "substance abuse"
jeff mills - "reverting"
joey beltram - "energy flash"
surgeon - "badger bite"
red planet - "journey to the martian polar cap"
