Music has provided an outlet for expressing the political vision of violinist and composer Klaus der Geiger (born Klaus von Wrochem). Performing as a street musician since 1970, Der Geiger has spoken out against housing shortages and the limiting of tenant and human rights. In addition to performing many concerts for the homeless, he has participated in numerous demonstrations against the transportation of radioactive whey powder into Third World countries.
A native of the small German city of Doppoldiswalde, halfway between Dresden and Dubi, Der Geiger studied in Cologne under American composer Mauricio Kagel. Traveling to the United States in the late-'60s, he attracted attention as a political-minded street musician in Boston and San Diego. When his request for a visa extension was rejected, due to his political outspokenness, he returned to Germany.
