Yuri Hatsuka is a nursery school teacher and child psychologist based in Sapporo, Hokkaido, Japan. Since 1993 she has been regularly recording music for her nursery school as she felt it supported her students' development and a calm approach to afternoon play. The recordings she has made were used in a handful of independent kindergartens and schools in Japan on a very low level purely as an educational aid for almost twenty years.

She eventually collated her series after gaining some demand for her work as '睡眠周期' (literally 'Sleep Cycles') but started recording more recently with friends who wanted to make calming ambient music for a variety of situations in their communities. After creating and using hundreds of hours of untitled music, the label 'Sleep Loops' was made to print titled albums in very low edition CD(r)'s that were used as an educational tool from 2011. We are thrilled that her wonderful music, and that of friends in her community, will now be made available through Modern Composers.

'Sleep Loops and Meditation I' is her first known work which was originally recorded and played directly on cassette (as the bulk of her recordings were) in 1992. She used this one day a week for almost a year before deciding to record weekly tracks from then on.

Thank you.
