The group was formed in 1992 and consists of brothers Shuya[1] and Yoshihiro Okino.

They have also included Hajime Yoshizawa, a piano producer, on a number of works.

[2] Although the brothers DJed in the late 1980s and were remixing and composing as far back as the early 1990s, they were largely popularised by the British Radio 1 DJ Gilles Peterson around 2001.

[3] Brothers Shuya and Yoshihiro Okino, both DJs and remixers in Kyoto, formed the project in 1994.

[6][7] Shuya Okino also runs a music venue in Shibuya, Tokyo, called the Room.
