Tokyo-based sound artist and improviser Makoto Oshiro carries out live performances and installations in which he creates sound using self-made devices and remodeled pre-existing objects. Beijing-based musician/poet Yan Jun, one of the leading Chinese artists on the experimental/improvised music scene, creates music and produces installations freely utilizing electronics, field recordings and voice.

This album was studio-recorded on February 22, 2017, when Oshiro was visiting Berlin and Yan Jun was in that city on a long-term residency. The two tracks are about 22 minutes each. The instruments listed on the album cover are "objects" (Oshiro) and "feedback" (Yan Jun). The noises produced include clattering, rotation noise and sustained sound. In Track 1, various low-volume noises are sent forth in a calm and simple way throughout the piece; while in Track 2, numerous multi-layered noises cover the space and also produce intervals of high volume. This album is remarkable not just for the straightforward expression of each artist's musicality, but also for the superb collaboration achieved in the performances.
