NTT DoCoMo - Knock on Wood - Phone Introduction

This could be one of the world's longest xylophones built in a Japnase forest to promote the natural elements and a new wooden phone being introduced by NTT DoCoMo.  The song?  Bach's classic Cantata 147.  The commercial is a nice simple idea.  For those of you who are my regular readers, my feelings about simple pieces are well known.... simple is good.  They shot the hell out of it from about 10 different angles.  According to the NY Times the soundtrack is original.  Elegant straightforward concept done well.
