Gerhard Rüdiger Gundermann, who generally performed as simply Gundermann (February 21, 1955 — June 21, 1998), was a German singer-songwriter and rock musician. An excavator operator, his musical career began in the former East Germany, where he became known for his clever, often melancholy lyrics imbued with social commentary. After German reunification, he became especially popular among former East Germans who felt disenfranchised in the reunited country.
Gundermann's first appearances as a singer-songwriter came in 1986, and a year later he won the grand prize and a recording contract in the East German national song contest. His first LP Männer, Frauen und Maschinen (Men, Women, and Machines) appeared in 1988, but in contrast to his solo acoustic performances it was a rock record with a backing band, with uptempo numbers like "Halte durch" (Keep Up). It included an ode to his hometown, Hoyerswerda, "Hoy Woy."
After the fall of the Berlin Wall, Gundermann ran unsuccessfully for a seat in the Volkskammer in the March 1990 elections, running for the leftist alliance Aktionsbündnis Vereinigte Linke.
Gundermann lived an ascetic lifestyle, eschewing drugs, alcohol, and smoking, and was a committed vegetarian. However, he was a workaholic, and slept little; besides a full recording and performing schedule, Gundermann continued to work operating a giant excavator, digging up seams of brown coal; he was worried that his music would lose its authenticity if it became his sole way of life. Perhaps because of overwork, Gundermann died of a stroke on June 21, 1998 at the age of 43 at his home in Spreetal. He left behind four children. His death followed that of his friend and collaborator Tamara Danz, also 43, by less than two years.
