In Do Not Sell at Any Price, Amanda Petrusich examines a unique subculture of record collectors: those individuals who devote their energies to 78 rpm records. The book’s title references the passion of these shellacphiles through the discovery of two rare 78s, both of which carry handmade stickers that declare, “DO NOT SELL AT ANY PRICE.” (Alas, this charge was not heeded.) Petrusich’s account is a sweeping one that encompasses not only the personality quirks of the devotees and the psychological nature of amassing found objects but also the production of 78s and even the cultural capital that has privileged certain musicians who were not the popular artists of the their day (building on Elijah Wald’s Escaping the Delta: Robert Johnson and the Invention of the Blues). As she begins interviewing these collectors, Petrusich gets swept into the fray herself, starting with a day at the Hillsville Flea Market—which occupies the entire town of Hillsville, Va.—and her mania ultimately leads her to secure scuba certification so that she can search for 78s purportedly cast into the Milwaukee River by employees of the long defunct Paramount Records plant in Grafton, Wisc., even if she emerges from the captivating enterprise with little more than “river sickness.”
