The Wise Guys were a German a capella band that was formed in 1990 in Cologne, Germany and split in 2017. Apart from Nils Olfert and Björn Sterzenbach, the members all attended the Hildegard-von-Bingen-Gymnasium in Cologne from 1981 to 1990. With their schoolmates Clemens Tewinkel and Christoph Tettinger, who also founded a brass band with them, they formed a rock band. At a school event, the band performed a single a cappella song. After graduating from high school with their A-levels (Abitur) in 1990, the group focussed on the a cappella genre. They soon named themselves the "Wise Guys". Eddi (Edzard) joined an 18-month alternative service for conscientious objectors in Brussels, which left the group as a quartet. The remaining four joined the Ersten Kölner Barbershop Choir. In early 1994, the group placed third in a Barbershop Quartet competition. However, this type of music was not representative of their later work. More information...
