Thirteen high-speed rock improvisations on drums, synth, piano & voice from the continuing collaboration of Magaibutsu label leader & drummer Tatsuya Yoshida and synthesist & pianist Risa Takeda, each track titled for Nordic mythology, the album title a reference to the World Tree, a giant ash supporting the universe; dramatic, amazing, unconventional instrumental music.

The duo of drummer Tatsuya Yoshida and keyboardist Risa Takeda take to the road in a 2023 summer tour, their rock-based improvisations energetically wild and masterfully controlled as they run through 11 pieces in a concert at Environment 0g in Osaka, the title referencing the capacity for some proposition or theory to be proven wrong; in contrast, this concert is quite right!

Fifteen rock instrumentals between drummer Tatsuya Yoshida and pianist & keyboardist Risa Takeda, generally high-speed, technically superb and melodically infused pieces of imaginative creativity with a quirky sense of humor, augmented with Yoshida's vocalizing and effect processing from both; includes a download sheet for 15 high-def movies, one for each track on the album.
