What a great initiative! I was always a fan of street music and the flair it gives to big cities like Paris, London or New York. I listened to the Alex LoDico Ensemble at Times Square and 42nd Street subway station. It was great fun, I just hope these guys get famous one day, seriously.
I agree, MUNY is awsome. How else would I discover talents like the Saw Lady (musical saw player) or Key (blues guitar/harmonica) or many other great musicians. They sure help pass the time waiting for the train.
