"Yoshio Machida (町田 良夫 Yoshio Machida?, born 1967 in Japan) is an experimental musician, a steelpanist, composer, and visual artist.

A member of ASCAP, Machida studied minimal art, music and film at the Tama Art University under Kuniharu Akiyama, Yoshiaki Touno, Sakumi Hagiwara and Kishio Suga. In the 1990s, Machida worked for an international cooperation in Asia and Africa.

Machida's first album Hypernatural (1999) had been featured with Brian Eno and Oval (band) on David Toop's article about Generative music. In 2001, Machida started to play improvised music by Steelpan with computer program Max/MSP. Machida has been invited to perform in ISEA2004, Sónar Tokyo, MaerzMusik and other venues. In 2004, Machida founded an experimental music label Amorfon. In 2007, Machida formed an electric Dub band miimo with tatsu and Norihide Saji. Machida also organized "Japan-Macedonia exchange art exhibition" and some workshops for children.

As a visual artist, Machida has produced Photobatik like Photogram technique using photographic paper. Photograms are produced by partial exposure and development of the entire photosensitive surface. Photobatik is "whole exposure and partial development." Machida has expanded his technique to overexposure of the photographic paper followed by only fixing the image, resulting in a pink image."

"Born in Montreal, Cal Lyall studied electronic composition and jazz performance in Quebec, eventually moving westward in Canada to teach music and perform. An interest in diverse musical forms led to intense travel and study throughout Southeast Asia and the Subcontinent, including lengthy visits to India, Pakistan and Iran. A visit to Japan in 1998 led to long-term residency in Tokyo, where he is currently active as a sound artist focusing on improvisation, folk music and urban noise.

Involved in the arts scene in Japan for over fifteen years, he has organized large-scale performances involving both Japanese and overseas artists, while also remaining a key member of a number of musical groups which have toured both locally and internationally. His musical activities are documented on over 30 albums he has both produced (including three full-length compilations released on medama records in Japan) and contributed to as a writer or musician. As a curator, he established the monthly Test Tone concert series in 2005 at Tokyo's SuperDeluxe. Featuring over a thousand distinct artists over its 9 year run, it reached its 100th installment in 2014.

With an active performance schedule in Japan and past tours through Thailand, Laos, Indonesia, China, Korea, Australia and the US, he also heads up the Subvalent record label and oversees the Tokyo Hub of Jolt Sonic Arts (Australia)."
