I've seen an uptick in subway performance art during the past six months. On Thursday afternoon coming back from the west side on Line 10 (BJ), there was a singer/guitarist who was downright good (and cool looking to boot). I couldn't muster the courage to take a video of his performance, but I wish I had because it was rather surreal.

But, in Shanghai, they've taken this concept to a whole new level: companies sponsor pole dancers to do their thing on the metro (Line 1 seems to be a favorite).
