Book excerpt: A celebration of the record stores and concert tours of the 1970s, arguably the greatest decade for music. 1812 Overture Record Stores provided a crystal ball's insight into the popularity of a band. It was through record sales where Alan Dulberger was able to discern which acts to book for concerts in the city. It proved to be an uncanny barometer, an indicator which led to sold out stadium shows by some of the largest touring acts in the world--Pink Floyd, The Rolling Stones, Eagles. It was the Eagles show at County Stadium, managed by Irving Azoff, that proved to be the death-knell for 1812 Overture Record Stores and Daydream Productions.
