Gintautas Gascevičius, better known as the drummer of the Lithuanian rock band BIX, has ventured into literature with his debut novel titled "Ka ir Ba." The book is described as a non-traditional urban novel where the city serves as a layered structure, revealing hidden dimensions of everyday life. It presents familiar locales as thresholds of deeper meaning, allowing ordinary people to become part of larger, ambiguous processes at play in society.

The story delves into the boundary between reality and the fringes of perception. In "Ka ir Ba," parallel realities do not merely serve as fantastical backdrops; instead, they emerge slowly and are almost imperceptible, akin to a crack in one’s vision. Readers are invited not just to follow the plot but to witness the very nature of reality beginning to double and expand before them, challenging their understanding of what is real.

According to Gascevičius, the city transcends mere geography, living in alternate layers that only reveal themselves when one starts to question their perceptions. This novel marks a significant shift for the artist, who has previously explored the intersections of sound, text, and philosophical thought, as seen in his music album "Schrödinger's Cat," which examined the themes of uncertainty.
