A video of 17-year-old DJ going by the name of “Madeon” performing a mashup live has gone viral… and for good reason. The kid has used samples of 39 songs and put the pieces all together into one cohesive track by triggering each sample using a sample pad. Give it a watch. It must have taken quite a bit of practise and memorization to push the right buttons at the right time for 3 and a half minutes.
