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. In contrast to her piano lessons as a child, which were limited to »memorization,« she now learns to play instruments (guitar, keyboard, or sewing machines) as a means of expression. She started her first band, Blendwerk, with Chris Janker, Roman Harrer and Rudi Fischerlehner completing the lineup. In 1997, their first demo cassette, titled Leroy, was published. The CD t0.or.at/~blendwerk followed in 1999 and, in 2001, the CD keine Angst (No Fear). The Neue Südtiroler Tageszeitung described their music with these 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 formed 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 a looper.
When asked what artists have inspired her,Plavčak names Frank Zappa, Captain Beefheart, and Talking Heads. Browsing through music reviews for descriptive words, one finds »post-rock,« »Noise,« »indie,« and »punk« as well as »experimental, progressive, and avant-garde.«
