Rafael Anton Irisarri is an Ibero-American composer, producer, and mastering engineer whose work moves through the overlapping territories of ambient, experimental, and modern classical music. Born in Puerto Rico and now based between Spain and rural New York, he first emerged in Seattle’s 2000s scene under the moniker The Sight Below, where blurred guitar textures and submerged rhythms met the skeletal pulse of minimal techno. His sound has since expanded into widescreen landscapes attuned to memory, geography, and the emotional weight of place.

His catalog spans early releases on Ghostly International to recent work on Black Knoll Editions, forming a sustained body of work that functions as an archive of atmospheres and afterimages.

Irisarri is the founder of Black Knoll Studio, a mastering house with a catalog that extends across contemporary experimental music. His engineering work has shaped recordings by Ryuichi Sakamoto, Terry Riley, William Basinski, Grouper, Julianna Barwick, MONO, and many others. Long-term collaborations with Abul Mogard and Benoît Pioulard (including three Orcas albums and multiple joint works) form a central thread in his practice.
