We tried playing something right there when we met (Beck Tang and me). It was not bad. A light grove (dadra) matched a melody Beck had in mind and we played amid the noice. Here is thtat clip on you tube. . http://ca.youtube.com/watch?v=VXL3PZBM038
Erhu is an amazing instrument and Beck played it very well. Its simplicity is unbelivable. It has only two strings and abunch of horse hair tied to a blow in between the two strings! .
