Infected Mushroom’s live performance only uses a MIDI keyboard. Some people are even better, such as David Guetta, who doesn’t use any props in his performance and looks serious. In fact, most of it was just cooking food there. I remembered the last time I was in a bar, a male waiter dressed as a waiter was cooking food on the disc player. My friends were all very excited, but I was the only one who was embarrassed.
