I gotta be honest... I thought this was how all EDM songs where made.
These guys literally took a store bar code scanner and hooked it up to a speaker. Then printed off barcodes in different patterns to create a song. It's actually pretty amazing. I'm now convinced this is what Zedd made and entire career off of.
This isn't the first time they've jammed out with barcodes, they've made several videos creating electronic dance music with a store scanner. Let me apologize in advance if you're behind me in the Kroger self-check because I'm now inspired.
