CMJ Music Marathon, RadioVision Festival, PopSpotsNYC's revisiting of classic album covers, Radio City Music Hall, Penelope Houston on New York City, the Metropolitan Museum of Art, and NYC-themed music videos by Robin Thicke and Sting  are among the items covered in this fourth installment in the New York State of Mind. This is the new Amoeblog series in which I report, from a New York City perspective, on music and other entertainment and happenings in the Big Apple.
