The great classical pianist Lang Lang is not above lending his name to various products -- Steinway youth pianos, silk scarves, and Adidas shoes -- to make some more money.
I just learned that Lang Lang has played some piano music for Rolex's watch advertisements. Rolex takes the point of view that the arts, sports, and their watches are all related. "Shamis K" has made a video compilation of Rolex ads with Lang Lang, ballet, opera, tennis (Wimbledon), and equestrian performances. I think it's very good entertainment, maybe even art.
Lang Lang has also given a hilarious demonstration of the mingling of art and technology. As the first of four encores to one of his concerts, he played Flight of the Bumblebee on an iPad.
