This “Eavesdrop” installment takes you to Thursday’s press preview of the exhibition Worlds Away: New Suburban Landscapes, led by co-curators Andrew Blauvelt of the Walker and Tracy Myers of the Heinz Architectural Center, in Pittsburgh. Installers were still painting, hanging work and gluing pieces together to get ready for tonight’s official opening. If you get the chance, also check out the previous Eavesdrop installment, where Blauvelt shows you the two- and three-dimensional models he used to put the exhibition together.
