This is 10 kinds of awesome. That being said, the musical credit of this should really be chalked up to the video editor and sound technicians. All the sounds were probably recorded one at a time with a person hitting the instrument. Then in post, the editor more than likely had to add the appropriate sound effect to the exact moment the car was hitting that instrument. There were waaay too many instances when the note continued to resonate entirely too long after the car had passed. Either way; awesome commercial, good job editor(s), and I wish something like this could actually be done in one real take.
