one headphone to the next, trying out different styles. The songs played are not listed in other places, giving listeners a chance to truly discover new music.

The only problem is that since none of the songs can be downloaded or even have names, the only way listeners can hear songs they fall in love with, is by visiting the "Listening Tree" over and over again! So far, this unusual way of discovering music has been a big hit with visitors. Its success largely results from the fact that the experience is both social and personal. One can visit the tree with friends. But as soon as the headphones are on, each member of the group can enjoy the song of their own choice.

The artist's characteristic ways of displaying technology have made it possible for audiences all across the country, to experience the ordinary world in unusual ways. We wonder what he will think of next!
