Combining nationalism with their nascent crate digging, the Polish duo of Marcin Cichy and Igor Pudlo revisit the roots of their country’s jazz scene on their second full-length. Full of symphonics for dark, smoky rooms, this impeccably made disc doesn’t radically alter notions of downtempo music as much as it fits in comfortably with Ninja Tune’s more solid output. On tracks like “Deep Breath,” tweaks to a fluttering horn line are so subtle it‘s hard to tell if the original performance included a trumpet mute or if it was touched up on a computer. Konfusion contains examples of Cichy and Pudlo at their best, creating spacious arrangements, like “Test Drive,” that jack up the natural drama of each individual jazz sample.
