Looking for a motivating, intense hard-driving 60 rpm climb? Look no further! This tune comes from an “industrial band” founded in 1984, featuring heavy guitar riffs, electronic music, samples and terrific female vocals! At 4:34, I use this toward the end of a climbing stage as I am having everyone watch their watts go up and equate it with HR, heading towards AT. Check out kMFDM “Professional Killer” (lucia cifarelli tribute).
