Nena promoted the release of Oldschool with a "clubtour" of 15 smaller venues (for 200 to 700 people) over 21 days in March 2015 [REF].
The concerts received overwhelmingly positive reviews, the common theme being the success of what Bild described as, "the mix of old school and new, pop, funk, new wave and '80s feeling" [REF].
