The people stood in the cold underground waiting for the late night subway that only comes every half hour. They are all strangers. He warms them with the sound waves he produces with his guitar. One by one they begin to turn around as the waves wash over and the tide slowly caresses them in. The people gather in a semi circle around him, inching closer to really feel the waves, each now a part of the collective moment. They started out all in their own mental worlds, now they have expanded and turned in and they are all sharing the same world. Some sing the words to the song on the guitar. Others bob their heads, or bounce along with the beat. Everyone claps earnestly when the song ends, and happily show their appreciation by filling his guitar case with love. He did this. He brought people together in a city that idealizes lone wolves. He created this world of shared collective joy.
