The fourth installment in the “for sleepless night” series. Piano pieces accumulated through daily practice during the pandemic. Recorded as ambient music and sleep-inducing music using live piano and cello improvisations, these tracks have been re-edited and fully completed. Some pieces exceeded 20 minutes, making them unsuitable for streaming. However, through editing, adding cello performances, remixing, and remastering, we present this as a grand work comprising 19 tracks.

Composer Mizoguchi finds ambient sounds highly effective and utilizes field recordings. The album includes:
M1 “Peaceful Noise” - Field recording of bird sounds
M11 “Bird Twitter” - Field recording of bird sounds
