"Motoharu Yoshizawa (吉沢元治) (1931 - September 12, 1998) was an influential Japanese bassist known for playing in a distinctive free jazz and free improvisation style, sometimes deploying electronics and using the unusual self-designed five-string bass he referred to as the "Tiritack".

Yoshizawa collaborated with innumerable musicians over his long career; some of the better known include Masayuki Takayanagi, Masahiko Togashi, Takehisa Kosugi, Mototeru Takagi, Kaoru Abe, Steve Lacy, Dave Burrell, Derek Bailey, Evan Parker, Barre Phillips, Butch Morris, Elliott Sharp, Ikue Mori, Keiji Haino, Kan Mikami, Kazuki Tomokawa, Christopher Yohmei Blasdel & Tenko.

Yoshizawa began playing in a free style in the mid-1960s, in groups with Yosuke Yamashita and Kazunori Takeda, as well as in a famous jam session with Elvin Jones during John Coltrane's Japan tour of 1966. Yoshizawa's own trio with Mototeru Takagi was said to have been pivotal for Japanese free jazz, though no recordings survive. In 1969, Yoshizawa played with Masahiko Togashi's famous quartet and Masayuki Takayanagi's New Directions group, participating in both groups' landmark recording sessions of that year.Yoshizawa was a pioneer of solo bass performance, his experiments synchronous with those of Barre Phillips. He first played this style in 1969, though nothing was recorded until several years later. In the mid-1970s, Yoshizawa recorded three albums for solo bass. Later in the decade he had a fruitful collaboration with alto saxophonist Kaoru Abe, which led to the recording of one album, Nord.

In the 1990s, Yoshizawa began experimenting with an effects-laden, five-string bass of his own design. He spent six months living and playing in New York in 1989-90.

"Kim Dae Hwan (김대환) was one of Korea's most renowned western style percussionists. He died 70 years old. It was very fast to be gone. We cannot forget his wildness and smile. At first He was a drummer of the first Korean rock group ADD4 formed by Shin Joong Hyun who is the godfather of Korean rock. Then he formed his own band called Kim Trio (the principle of this band was never performing the same songs), and so on. He joined the first Korean free music group Kang Tae Hwan Trio in 1978. After that, he had performed by solo musician, and collaborated with many kinds of artists till his death. And also he was a famous calligraphist. His work, 346 letters on a gain of rice, appears on Guinness Book. He had performed calligraphy on his stage every time. Only this was his leader album put on the market formally before he died. He played very simple drum sets that constructed with a roto-tom and cymbals and Korean traditional drum, with six sticks in his hands. It was very silently. Above his drum sound, haegeum (Korean traditional instrument) by Mrs. Kang Eun Il was crying bitterly or weeping gently."
