Katrin Plavčak makes music simply because she loves being a member of a band and enjoys collective creation compared to the isolated work of a painter. For her music has to »rock,« and the lyrics need »to have a clue.« Texts in English are important, as well as the structure and a »unique tempo« in the songs. Compared to her piano lessons as a child, which were limited to »memorization,« she learns to play instruments (guitar, keyboard, or sewing machines) as a means of expression today. She founded her first band Blendwerk with Chris Janker, which was completed with Roman Harrer and Rudi Fischerlehner. In 1997, the first demo cassette, titled Leroy, was published. The CD t0.or.at/~blendwerk followed in 1999, and, in 2001, the CD keine Angst. The Neue Südtiroler Tageszeitung described the music of Blendwerk with the following words: »Electro beats, feedback guitars, neurotic vocals. Those are the elements that come flying at one when listening to the demo cassette Leroy.«
When she moved to Berlin, she started a new band, the Erste Stufe Haifisch (with Elis Bihn, Jens Rockstroh, and Rudi Fischerlehner).
In 2016, Plavčak started performing with Ulrika Segawerk as M.O.G (Mothers of God). The duo appeared on stage with used sewing machines and electronic pickups, and looper.
When asked who her musical inspiration is, Katrin Plavčak names Frank Zappa, Captain Beefheart and theTalking Heads. Browsing among music reviews for descriptives, one can find »postrock,« »Noise,« »indie« and »punk« as well as »experimental, progressive and avant-garde.«
