January 2025, Osaka contemporary art gallery ‘Gallery Nomart’ hosted Hideo Takashima's solo exhibition ‘Fill with Empty’. This was Takashima's first exhibition at Nomart, and featured the first live collaboration between British heavyweight drummer/percussionist Roger Turner and sara (.es).

The exhibition title ‘Fill with Empty’ refers to ‘a state filled with margins that contain diverse possibilities,’ according to Takashima. Takashima explains that the exhibition title, ‘Fill witt Empty’, refers to ‘a state filled with margins that contain diverse possibilities’. The live performance was linked to this  theme. The two musicians, performing together for the first time, stood ready on either side of Takashima's enormous sculpture. Without any prior discussion, the album captures the real and fresh way in which the two, simply placed in the space, gradually began to resonate with each other. Having felt an immediate rapport during their one-off session, Roger & sara will return to Japan from the UK in January 2026 to perform live in celebration of the album's release.
