Fritz Rau (March 9, 1930 in Pforzheim, Germany - August 19, 2013) was a German concert- and touringmanager. He organized ca. 6.000 concerts in his 50 years of business life.
Rau organised the infamous Mothers concert in Berlin, 1968, which ended in a riot. Zappa later immortalized this event in his composition Holiday In Berlin, Full Blown. Although Zappa vowed that he would never return to Berlin again, Rau managed to change his mind.
