For many people in Bonn, particularly teenagers and students, the Stadtgarten season at Alten Zoll is already an institution. An extension almost of the numerous teenagers often seen and heard in the shade of the University trees strumming guitars as the sun goes down. I’m sure that opening act in 2018, Cynthia Nickschas, has been one of those strummers. This time around though she had an audience of well over 2000 picnicking on the grass beside her. French electro Folkies Fergessen, Indie-Rockers Koj and Jazz quartet Radius completed the opening weekend of music under the setting sun.
