It's been months, but I've finally started playing in the subways again. it feels really nice to get back to it. It's amazing how much time of day & location really influence the experience. My overall favorite spot to play so far has been Union Square - I feel like there's always a great mix of people there who get into the music.
It's been a bit slower getting back into it, but also, very refreshing ... It's very interesting for me to see how I've developed different music over the last year or two, and how I've something I did a year or two ago & added a new twist to it... it's also interesting to see how everything get's faster & faster the longer I play it (sometimes that's good ... sometimes not so much) ... a lot of the time my compositional ideas come from playing in the subway too (I'd say most of them really...)
Take this video: http://www.youtube.com/watch?v=ExR8dWkb6pc&feature=plcp - I do all the same stuff, but now I have the loop station drone under it & I add a middle eastern sounding section influenced by Gladiator to it
The truly great thing about the subway though is the people you run into - the old friends, the kids, the people whose day you made, the people who dance as you walk by, the whackos, everyone...
I hope to be sharing some of *those* stories in the near future!
