Vera Brandes (born 1956 in Cologne) is a German music producer and researcher in music and media effects. Life and impact. Brandes began to organize jazz concerts and tours at the age of fifteen, one of the first being a tour with Ronnie Scott's trio. In 1974 she organized the New Jazz in Cologne concert series in Cologne. The fifth concert in the series was the legendary "Köln Concert" by Keith Jarrett on January 24, 1975, which the pianist wanted to cancel because of an insufficient grand piano and fatigue. The concert took place only at the persistent urging of Brandes.
