Drummer-led bands can be a thumping bore, but not when Seb Rochford is the one behind the traps. He lends this seventh album from the London avant-jazzers an unerring but playful pulse of gentle polyrhythms alongside Tom Herbert’s taut, dub-like acoustic bass. The urban electronica of 2014’s In Each and Every One is sidelined for a spacier, more minimalist sound, no doubt influenced by the Mojave desert where Rochford mixed the record. The group’s twin saxes are sinuous but restrained, edgy but never ugly, and there’s a glorious singalong on Don’t Let the Feeling Go. “Love and positivity” are Rochford’s intent, and it shows.
