Kata Kovács and Tom O’Doherty (often also referred to by the stylised abbreviation KKTO) are an artist duo, primarily known for working with sound and duration.

Their initial collaborations were on a series of performances involving the acoustic traces created by movement scores, which were presented at Sophiensæle, ausland, Uferstudios, Montag Modus, and other venues in the city.

Black Emperor, involved receiving live signals from an abandoned satellite, the LES-1, as it orbited the earth above the site of the work, and combining the sound produced from these transmissions with music derived from sacred harp singing.

The work was an installation in which all the concerts in the 2016 Kiezsalon series were recorded, and then replayed in overlapping fragments, in the giant basement space of the Musikbrauerei, “evoking recognisable parts of past events, now juxtaposed with each other and situated in a radically different environment.” The work included excerpts from live performances by Christina Vantzou, Laraaji, Janek Schaefer, and others.

Both are also active in other musical and artistic collaborations: Kata Kovács is a member of the improvisation ensemble Vrouw, Tom O’Doherty has worked with Paula Matthusen and has exhibited photography.
