I usually get annoyed as all get-out when I have to deal with the panhandle-music performances happening at any given time in the NYC subway system. Call me a Negative Nancy, but when you're in an underground station, the acoustics are horrid and the music bounces off the walls infinitely, and after a long day, it's not amusing.
HOWEVER! There's a new band in town:
THE XYLOPHOLKS. Click to view
Where's the banjo-playing chicken?
I've yet to see these guys, but it's awesome.
