"X" is one mighty and truly legendary studio album from September 1978. On these 6 tracks that were dedicated to Nietzsche, Trakl, Herbert, Bach, Kleist and Ludwig II, Klaus Schulze made clear that he was the master of synthesizer music, after one German magazine counted Schulze second to Michael Rother, in the list of the most popular German musicians.
The line-up for the "X" album was : Klaus Schulze (Big Moog, PPG Synthesizer and Sequencer, Mini Moogs, ARP Odyssey, Korg Poly Synthi, Poly Moog, EMS Synthi A, Mellotron, Tom Toms on "Friedemann Bach", Tom Toms and a cymbal on "Heinrich Von Kleist"), Harald Grosskopf (drums), Wolfgang Tiepold (Cello on "Heinrich Von Kleist") and B. Dragic (solo violin on "Friedemann Bach").
