Call Book isolates and magnifies human broadcasts on amateur radio—little phrases, sentences, or vocalizations that might otherwise be forgotten. Palombo’s belief that “there’s something to be learned from every human interaction” focuses the work on cementing these unnoticed moments in the imagination of the listener. “Shortwave radio,” she says, “isn’t just harsh frequencies, number stations, or signal interference—it’s also a longstanding method of communication”

While making the piece, Palombo would record small pieces of chit chat, mouth sounds, or conversation and build elaborate compositions around them, framing the source material into more than just passing sounds or words. - Described by Wave Farm Radio Art Fellow 2023, Lia Kohl.

The Wave Farm Broadcast Radio Art Archive is an online resource and broadcast series on Wave Farm’s WGXC 90.7-FM, which is syndicated to stations across the country through The Radio Art Hour. It aims to identify, coalesce, and celebrate historical and contemporary international radio artworks created specifically for terrestrial AM/FM/Shortwave broadcast, whether it be via commercial, public, community, or pirate transmission. The archive is a product of Wave Farm's Radio Artist Fellowship.

Radio artists explore broadcast radio space through a richly polyphonous mix of practices, including poetic resuscitations of conventional radio drama, documentary, interview and news formats; found and field sound compositions reframed by broadcast; performative inhabitations/embodiments of radio’s inherent qualities, such as entropy, anonymity and interference; playful celebrations/subversions of the complex relationship between senders and receivers, and the potential feedback loops between hosts and layers of audience, from in-studio to listeners at home to callers-in; use of radio space to bridge widely dispersed voices (be they living or dead), subjects, environments and communities, or to migrate through them in ways that would not be possible in real time and space; electroacoustic compositions with sounds primarily derived from gathering, generating and remixing radiophonic sources. Note: Wave Farm continues to expand this definition of radio art through engagement with contemporary practices including those revealed by Wave Farm Artists-in-residence, and the Radio Art Fellowship program.
