Konrad "Conny" Plank (1940-1987) was one of the most innovative sound designers and music producers of his time. The recordings, which were created in the legendary recording studio in Wolperath near Cologne from the 1960s, have revolutionized the music world. He was the pioneer of the Krautrocks and pioneer of electronically influenced pop music. Bands and artists like NEW !, Brian Eno, David Bowie, Ultravox and the Eurythmics took up with him and emphasize the influence he had on their music. Without Plank, Gianna Nannini would probably have sung in English forever, and if a certain Bono had been more sympathetic to him, "U2's" Joshua Tree "would sound quite different today.
