I listened to the video for a full 20 seconds. While the visual may seem modern, the music (and the audience clapping) were 100% traditional. Granted, the chick-chick-chick sound came from a trap set rather than from a shaky egg, but as a sound it is nothing new.

No doubt they will do something more 'modern' later - if you can call present-day rock, which doesn't seem to have done anything new since Jimi Hendrix, modern.
