A double CD of Japanese pianist Miharu Ogura's performance of Karlheinz Stockhausen's Klavierstücke I-XI for solopiano, recorded at the MONOPIANO festival in 2021, bringing to a pinnacle her fascination with Stockhausen's unique approach to this set of compositions, captured in her second live performance after a concert in Tokyo in the same year.

Stockhausen's late 60s composition "Mantra" was a return to his intricately systematised approach to musical construction, expanding the possibilities and potentialities of the serial principle to allow for more melodic and embraceable compositions.
