At first when I saw this I was like pppth, another Mario-themed classical music arrangement, YAWN. That's how jaded the internet has made me.
But this is actually delightful. The violinist mimics not only the music but the sound effects we all know and love, like the "boingboingBOING" of the mushroom and the frenzied double-time of Star Power. It ends, of course, with the terrible dirge of Mario spiralling to his death. But that's ok! You have two more lives.
Also, that is a snazzy outfit, violin man.
