*200 copies limited edition* Born in 2000, Sun Yizhou is an up-and-coming improviser/composer based in Beijing. In 2022 he released the CD "Responses" (on the Japanese label zappak), a collaboration with fellow Beijing resident Zhu Wenbo. Kevin Corcoran is a San Francisco-based percussionist who also uses field recordings and electronics in his musical projects. He has carried out tours in Europe as well as Japan and other East Asian countries.

The four pieces on this CD (each about 13 minutes long), based on graphic scores by Sun Yizhou, were produced through online exchanges between the two musicians in June-July 2022 and mixing by Sun. While there are scores at its foundation, the music has strong improvisational elements. Sun used electronics; Corcoran used percussive objects. The various sounds produced by the two musicians run in parallel while interweaving and going through several transformations. The layering of multiple sounds is exquisite, and the finished works are extremely rewarding.
