Gifted Belgian jazz pianist, improviser and composer Casimir Liberski joins forces with renowned Japanese drummer and composer Tatsuya Yoshida, founder of the group Ruins! In 2022 Liberski and Yoshida performed in a very small club in Tokyo called Thelonious. Yoshida recorded the concert, giving birth to the album. Under John Zorn's recommendation the album was creatively mixed by James Dellatacoma and mastered by Michael Fossenkemper. The visual artwork for the album features a painting by the Belgian artist Pascal Bernier.
