The coolest act I have seen by far happened at the W 4th stop of the F train after the Ting Tings show on March 16th. It was two people, one black guy with dreads playing the guitar and one white girl dressed like a gypsy in a pork pie hat playing the washboard with a bell and singing. She was so entertaining to watch, she sang with such expression, think Audrey Tautou's face throughout 'Amelie', and all of their songs were catchy. They made a VERY diverse, late night crowd all stop and listen and even throw dollars, not loose change, their way.
So keep your ears perked, pause your ipod more often, and if you find this duo somewhere in the underground world, give me a holler!
