In this video from the NYC subway, a singer named Jessica Latshaw, bearing a small uke, finds herself sitting across from a gentleman with a fine pair of bongos. The two begin an impromptu jam session, emceed by a random gregarious stranger and captured for posterity by a subway rider with a camphone. The performance is just fine, and it's clear from the footage that the rest of the car is having a fine time.
In theory, it's possible that the whole thing is a fix, "buzz marketing" from Latshaw and co, and if so, well, it's an extraordinarily nonobnoxious example of the form.
okay- what you are about to watch is a true new york experience. what originally started out as a typical nyc subway ride (sitting across from guy who smelled like urine) turned into an awesome performance by two people who have never met before. i captured the whole thing on video.
never a dull moment on the nyc subway
