I was just nine or 10 years old when my elder brother brought home Made In Japan. I’d already heard Deep Purple’s In Rock and Fireball, both of which had affected me in Biblical proportions. For some unbelievable reason I wasn’t familiar with Machine Head, the studio album that so much of Made In Japan is based on. I went out and got Machine Head because I had loved Made In Japan so much, but as a naïve little kid from Sweden I couldn’t understand why Lazy and Space Truckin’ had suddenly become so short. No other live album had such a huge impact on me. Made In Japan had so much crazy energy, man. Back then, without the internet, MP3 players and thousands of radio stations to choose from, hearing a new record for the first time was such a religious experience. I actually wore out three or four copies of the vinyl edition.
