These albums contain recordings of Bertoia sounding sculptures. Each album has one “song” per side. Sample titles include “Gong Gong,” “Mellow Tops,” “Space Voyage,” and “Vulcans Play.” Text on the album jacket by D’Otrange Mastai reads “Monotony is ruled out, since there can never be an exact repetition, and it is obvious also that the familiarity of possession would not bring about a surfeit but rather heighten and deepen the spell.”
