| | | In preparation for the 1988 USA tour, as well as co-composing a title for the album Optical Race, Edgar Froese and Paul Haslinger were joined by Ralf Wadephul, a studio musician from Berlin. He was to complement them on keyboards, and in the studio this worked well, but unfortunately, there were irreconciable differences during the USA tour and this collaboration then ended in 1989. Hereafter Ralf Wadephul worked as a sound technician in Berlin. |
