She is a very talented author and vocalist. In late 90's she used to be the voice of a very multi-platinum pop band – Varius Manx.

Then she decided to start her solo carrier – she released two solo albums with soft and ambitious repertoire. Apart from being a great performer, Kasia is also well known as a composer and lyricist for other artists (including famous Polish singer Kayah) and herself (almost all songs of Varius Manx and on her two solo albums were created by her). She has also some success with music for TV and Cinema including the title song of Polish TV Series "Londynczycy" (Londoners).

So far, she has recorded four solo albums and has currently completed her newest album "Lucy and the Loop".
The album is co-produced by Eddie Stevens who is known for his cooperation with bands as Moloko, Roisin Murphy, and Zero Seven.
The album is a mixture of electro and acoustic music emphasized by English lyrics. Both the music and the lyrics are very electrifying and inspirational.
