Wir machen gern ein T-Shirt für euch." ("Sure. We'd love to make a T-shirt for you.") That enthusiasm perfectly reflects a relationship that started long before this anniversary.

 Dr. Walker is an artist, musician, and electronic music producer who has had a major influence on the underground techno scene in Germany, particularly in Cologne (Köln). He is a co-founder of the legendary [Kompakt](https://kompakt.fm/) record label. He is also a co-inventor of the outstanding Zen Delay, a popular effects box used live on stage by many electronic musicians. If you have ever played a minimal techno track or used a hardware delay to make your transitions sound spacey, you are enjoying the culture Dr. Walker helped build.
