Harald Grosskopf was in his early twenties when LSD 'blew [his] reality away,' as he recalls. Born in Hildesheim in 1949, he had previously drummed in fairly conventional rock bands, most recently for Wallenstein. Their label-boss Rolf-Ulrich Kaiser was fond of facilitating jam sessions for musicians on his Ohr und Pilz label, often supplying his 'cosmic couriers' with LSD (unbeknown to them, on occasion). In one such session, the drug inspired something of an epiphany in Grosskopf: 'There I was playing the drums when, in the midst of my euphoria, I realized that I had been imitating other drummers. Suddenly a voice spoke to me: stop trying to sound like Billy Cobham or Ginger Baker. From that moment on I felt liberated, free to drum without having to shine in a particular role.' Having discovered his own musical identity, Harald Grosskopf understood that a standard rock combo was not the ideal conduit through which to express it. Grosskopf: 'I was completely in thrall to electronic music and the total freedom that it offered. This was the music I wanted to create. I knew it would be a success, the energy levels were so high.' Grosskopf consequently left Wallenstein. 'I fell into a hole at first, wondering what I was going to do. So I sold my prized drum kit and used the money to buy a guitar, amp and echo device.' A few days later, the doorbell rang.
