Miss Nelson & Bruce Haack - Dance, Sing & Listen Again LPEsther and Bruce ran dance classes for kids in the 1960's and 70's. Miss Nelson instructed the kids to act out a bunch of fabulous stories that move from the surreal to the sublime, at times being quite psychedelic. Meanwhile Bruce accompanied her on his wigged out homemade synthesizers creating an overdriven, robotic din that has not been bettered since.
