The sound artist Trimpin is the subject of a two-part interview and profile newly uploaded to the Other Minds archive at archive.org. Back in 1990, Charles Amirkhanian, head of Other Minds, spoke with Trimpin in advance of an installation due the following year at the San Francisco gallery New Langton Arts. Trimpin talked about his association with player piano innovator Conlon Nancarrow and about the compositional and technological innovations required for him to accomplish his often room-size musical sculptures, and Amirkanian illustrated with excerpts from various works, including “Lullaby,” a transparent piece for piano. Trimpin also took questions from a live audience. Among other things, he explained why he felt it’s “inappropriate” to document his installations on commercial recordings. Available in two parts (MP3, MP3).
