After a four-year sabbatical, Chicagos very own organicore (my term) ensemble has returned as if lead nerds Sam Prekop and Archer Prewitt had never done their sublime solo outings. Its a timely return for this quietly influential band meaning, influencing people who have no idea theyve been influenced (ahem, the, ahem, Shins). While no means up to the level of their early masterpieces One Bedroom and Nassau, their new disc washes in like a cool indie-pop tide, with the trademark high-whispering vocals of Prekop and a delicately layered acoustic sheen (salted and peppered by ex-Wilco producer Brian Paulson) setting the mood on the willowy first track Up On Crutches. The delicately propulsive Crossing Line embosses Mystery To Me-era Fleetwood Mac with a slightly off-kilter electronic muzz and knotty pan-fried guitars. All told, this is a record that may initially seep in one ear and expel like cigarette smoke out the other. But wait awhile.
