The Reeperbahn Festival in Hamburg is one of the biggest music events in Europe. A good place to show up and promote yourself as an uprising band. The challenge: how do you stand out between hundreds of other bands and acts? You go real underground! For Danish synthesizer rock band TURBOWEEKEND, their upcoming new album "Shadow Sounds" and their gig during the Reeperbahn Festival we created an unseen and suprising stunt. Several manholes right next to the festival had been prepared to detect passersby and give them a glimpse of TURBOWEEKENDs musik. Shazam not just showed the new album and the bands social media accounts but also the gig and where it was located. The result: a sold-out gig at the Festival and hundrets of new fans on social media.
