Subway musicals

I'm infatuated with the subway system in New York. It's not quite as friendly as anywhere else I've been in the world, but it's unique. My brother likes to call the NY subway "the Underworld", because it is a whole world, a maze of levels and layers of iron and steel... And musicians, with whom I am most (again) infatuated.
In DC, where my brothers live, the subway is civilized: Wishshshshshhh, the train enters the station, people file in and move away from the doors after waiting for the people inside to descend. Everyone has their earphones on, but there is no sound coming out from them. Civilized music levels. The doors close silently. Wishshshshh, and the train is off. The sanitized version of subway experience in suit-filled DC.
In New York, the subway is alive. The conversations abound, waiting to be eavesdropped on (see below the chica and her elvis impersonator). The city is alive, moving, bustling and kicking, over and under, not to mention the chaos which is the subway on Halloween, something I had the (mis?)fortune of witnessing this year. The artists are of all ages, races, and styles. There are the painful ones who murder their instruments and torture my ears (I wanted to snatch away a musician's violin once, the squeaking carriage was a more welcome sound). Rats scurry around happily oblivious to incoming trains. And then these musicians, who want to practice without bothering the neighbours, or make a buck or two, offer you a soundtrack to your life. Below are a few including a Christmas special that I managed to catch on my low resolution phone, and I apologise to the viewers/listeners, as well as to the artists about the audiovisual quality.
