Brand new? Mysterious as the origins of the Peruvian scissor dance? Well neither. OK fairly new, fairly mysterious. The newish bit is that prog-jazz thrash improv outfit Killing Popes since last year have had ECM keyboardist Kit Downes as a member, the codebreaker link via co-leader Swedish bassist Petter Eldh who is in Downes’ band Enemy. The other co-leader, and sharing the composing role, is drummer Oliver Steidle who surfaced in the trio Klima Kalima more than a decade and a half ago. Worth wrapping your ears around and turning up.
