The Liza Béar Avalanche Magazine Archive at MoMA (1971) documents the professional relationship between the Avalanche co-founder and sound artist Max Neuhaus, focusing on his transition from musician to sound artist [1]. The collection includes correspondence and black-and-white photographs of his "Water Whistle" series, providing crucial visual documentation of his shift toward conceptual, ephemeral sound works [1]. You can explore the finding aid for this collection on the MoMA website.
