Known mostly as a saxophonist on the Japanese improvised music scene, Junji Hirose has also released a series of albums using self-made analog noise instruments, here using a device where balls and small objects are placed on a large, shallow, round metal plate and moved by a compressor, here in four tracks with different objects and one with no objects at all.

Three days of improvisations from the the 2019 meeting of Osaka-based musicians mizutama, Tadashi Yonago and Kayu Nakada, plus Tokyo residents Junji Hirose, Toshimaru Nakamura, Daysuke Takaoka and Yuma Takeshita in duos and trios, all using original sound-producing devices or creating sound by repurposing instruments or electronic devices in unique ways.

Three free improvisations at the burning heart of the Japanese Free Improv scene from the trio of Junji Hirose on sax, Yoshinori Mochizuki on bass, and Ironfist Tatsushima on drums, balancing two tracks of frenetic playing with a lowercase extended instrumental piece.

Saxophonist Junji Hirose met Kazuhisa Uchihashi at Foxhole in Kichijoji in 2014 and 2015, Uchihashi performing only on Hans Reichel's daxophone--wood shapes played in a variety of ways to create unusual sound--as heard on these 10 surprising and wonderfully idiosyncratic recordings.
