June the 2nd is an important date to save, circle and keep open, if you’re a New Yorker (even in spirit) and love live music. Not just live, either. But also creative, quirky and not even faintly over-familiar. On this evening, at the Hi-Fi Bar (169 Avenue A) in Manhattan, Dave Foster will be throwing a hell of a party. One of Manhattan’s musical treasures, a songwriter who sews together swatches of sound, pieces of Pop from several eras, Foster will be presenting Song Of The Week, live, with a righteous multitude of great musical friends.
