"Not many Greek improvisers have made names for themselves on the European free music scene; Nikos Veliotis did it by connecting with British musicians in the late '90s while researching issues relating to the performance of graphic scores at Trinity College of Music in London. As a cellist, Veliotis is manifestly interested in extending the sound-making possibilities of his instrument. He's a member of the trio Cranc with harpist Rhodri Davies and violinist Angharad Davies. He's also played with the London Improviser's Orchestra and in duos with guitarist John Bisset and cellist John Wastell. Veliotis is a dedicated performer of contemporary classical works by composers such as Xenakis, Sculthorpe, Cardew, and Bussotti. He's also a member of Texturizer, a duo with Greek electronica artist Coti K. Veliotis has played on an ad hoc basis with Evan Parker, Fred Van Hove, and John Butcher, among others. His solo album, Cello (2001), was issued in limited edition with 100 CDs on the Confront label. Veliotis was the curator for the Athens offshoot of 2:13, a pan-European improvisation club that also has branches in London and Berlin."

"Ryu Hankil (류한길) was born in 1975 in Seoul, South Korea. He worked for about two years as a professional graphic designer. Hankil was a keyboard player in two famous Korean indie pop groups, but eventually left the groups because he was tired of typical music making and sounds. Then he started his own solo electro pop project, Daytripper, and released two solo albums, A Collector (2001) and Brownpaper (2004).

When he made Brownpaper, Hankil collaborated for the first time with the Korean noise / improvisation duo Astronoise. At that time, he saw a concert by Otomo Yoshihide, Sachiko M, Axel Dörner, and Taku Unami in Seoul. He changed his musical instrument and concentrated more and more on improvised music. Hankil has organized a monthly event called RELAY since 2005. He established his own publishing office called Manual, and releases improvised music and magazines.

Hankil uses clockworks as an instrument. He is interested in finding musical structures and so on in the vibration of objects. He focuses on using non-instruments-abandoned objects like old telephones and typewriters."

His work "since the early nineties... has been investigating the edges of ultraminimalism in both his composed and improvised work." He also operates B-Boim, a CD-R only record label focusing on improvised and composed music, much of it his own."
