Have you heard of JJ Lin? Singapore-born and based in Taiwan, he's an enormously popular performer and producer in that part of the world. He posted a video to his YouTube channel of him and his pal Apple CEO Tim Cook jamming in GarageBand with those new Chinese-music loops and instruments I wrote about yesterday. Mr. Cook serves as DJ in the piece, tapping loops to create the background music while JJ Lin plays the lead melody on one of those new instruments. It's fun, and it's a message aimed at the Chinese market. Also, note that JJ Lin posted it, not Apple and not Mr. Cook. Seems like Apple really is learning more about how to operate in that market.
