We're not knocking this guy for his ability to play a mean accordion. It obviously requires a great deal of skill, dexterity and rhythm. We're just wondering why someone this talented would choose to tackle an instrument that the United Nations recognizes as a form of physical and mental torture.
Being a master of the accordion is just a step above being a master of the bagpipes, a master of the slide whistle or Kenny G. You may have a unique ability to play these musical instruments, but the entire hearing world would prefer that you didn't. However, being able to play it faster is a plus because it gets you to the end of the song quicker and there is a greater chance that you might break the instrument, assuming that we haven't already done that for you.
