I've had a string of excellent subway music encounters that warrant sharing: A melancholy, yearning, embellished cover of Gloria Gaynor's I Will Survive played on the marimba at the 7th Ave F stop in Brooklyn.

Not the theme to Laura, but something very close, very Hollywood, played on an erhu at the downtown Prince Street R stop in Manhattan.

A middle aged guy in a Hawaiian shirt, sunglasses and loafers, enthusiastically and unabashedly playing air guitar AND air drums, including kick, to whatever was on his iPod, somewhere on the uptown N train.
