Kassel Jaeger’s works are a complex balance between concrète experimentalism, ambient noise, and electroacoustic improv. He has released several well-received albums on various labels including the boutique CD imprint, Unfathomless, the Italian experimental label, Senufo Editions, as well as Editions Mego where his fifth album, Deltas, was released on vinyl. In Deltas, Jaeger explores geological associations with sound, a theme he expanded in an installation for the exhibition Multinatural Histories at the Harvard Museum of Natural History. He used eight channels in the mineral room to make mineral resonances audible. He also runs the tiny Antisolar label producing small-run endless loop cassettes tapes in series.
