The one-man band is a rather ridiculous idea, drawing up images of one person attempting to manipulate several instruments, at once, in a vain attempt at creating music. It's usually represented by silly scenes like this. Interestingly, the concept isn't much more successful when the "man" in "one-man band" is replaced with "car," as we see in this video.
It seems that someone rigged up and edited (699 times, we might add) a Ford Fiesta, a bucket, 12 PVC pipes and the natural sounds that a car makes to come up with a song. Now, we don't recognize the tune, so we've no idea if this is a cover or an original piece. And while it's hardly Beethoven, we have to admire the amount of effort the "conductor" went to in his attempt to turn a subcompact car into a musical instrument(s). Take a look (or listen) below for the entire video.
