Barcode DJs Are Sound-Bombing Grocery Stores

Inspired by the incessant beeps of a cash register, Košice-based artist Jakub Pišek gathered his friends for a DIY grocery store performance called Barcode DJ. By scanning all kinds of stuff in the aisles while armed with a cart full of speakers, they make music by scanning barcodes. And they won’t leave the grocery store until the sound art is finished (that is, when they’re approached by store management).
