46,000 Fibres are a UK-based improvisational group, formed in 1993 out of a collective called Koven-oe, which originally included Robin Rimbaud (aka Scanner). Following Rimbaud's departure, the remaining trio of Richard Clarke, Tonal Davidson (aka Tonal D), and Leon Maurice-Jones shifted from structured material to explore electro-acoustic free improvisation. Operating on a philosophy of pure musical telepathy - foregoing pre-arrangement or discussion to create "something unique" without clichés - their sound evolved into diverse landscapes ranging from ethereal delicacy and gamelan stylings to hard industrial, space rock, radical jazz, and dark funk. While the lineup remained fluid over the decades, centered around the core of Tonal D and Leon Maurice-Jones, the group has maintained a rich history of collaboration with avant-garde luminaries such as Nik Turner, Lol Coxhill, Scanner, and Ashley Wales. Best Kept Secret, a retrospective of the group's live recordings made around London between 1993 and 2003, is out on Infinite Expanse in November.
