Maciej Markowski studied mathematics at the University of Wrocław and graduated from the State Secondary School of Music in Wrocław. He co-founded Małe Instrumenty (Small Instruments), a band focusing on sound exploration in the realm of professional small-sized instruments, sound toys, his own instrumental inventions and other small sound-producing objects. The group’s first album was Antonisz, which contained compositions from the animated films of Julian Józef Antonisz, recorded in new interpretations. In 2008, the group received a Tucan OFF award at the 29th PPA (Przegląd Piosenki Aktorskiej, Review of Stage Songs) for its performance Elektrownia Dźwięku (Power Plant of Sound) – a sound story about fictional ways of transforming sound into light.
Markowski also played in the band Kariera, with which he released the albums Miasto (City, 2011) and Kołysanki (Lullabies, 2014). He co-created the project Pieśni przepiękne (Beautiful Songs), for which he received a Tucan OFF award at the 36th PPA in Wrocław. Together with four amateur musicians, he created the ironic-experimental pseudo-shanty band Shantharion. He makes music videos (Manekiny [Mannequins] and Koniec wakacji [End of Vacation] for the band Kariera) and creates and programs multimedia installations (Odtwarzacz miejski [City Player], Kwartet na pomidory [Tomato Quartet], Lustra [Mirrors]).
He has collaborated with, among others, the Muzeum Współczesne Wrocław (Contemporary Museum), Wrocław’s Teatr Muzyczny Capitol (Capitol Music Theater), BWA Wrocław (Biuro Wystaw Artystycznych, Office of Artistic Exhibitions), Poznań’s Centrum Sztuki Dziecka (Children’s Art Centre), the Wro Art Centre and Warsaw’s Centrum Sztuki Współczesnej (CSW, Centre for Contemporary Art). He runs the leisure and creative work centre Czerwony Dworek 8 (Red Manor House) in Karkonosze, where he organises, among other things, the annual John Cage Mushroom Festival.
His soundless sound sculpture is a part of Polish Pavilion at the Gwangju Biennale in 2024.
