And Mach 2 takes off. The tracks that made Made In Japan such essential wax are here on Machine Head. Listening to it again is to be inside the heavy metal engine when it was so brand new it had yet to be labelled as anything like a genre, and getting to know what made it hum and roar. No disrespect to "Smoke on the Water", but "Highway Star" is in the Machine Head garage. Must have.
