Without doubt or qualification, The Sadies are one of this continent’s greatest extant rock ’n’ roll bands — just as they have been for the last quarter-century. Versatile and imaginative, they skip from astral psychedelia to shuffling bucolics and leap from puckish pop to righteous garage-rock without losing momentum or mastery. Their albums deliver masterclasses on pointed songwriting, lockstep harmonies, and a devil-may-care attitude to expectations and past successes. They will release a new album in fall 2021. So go on, pull up that screeching wooden chair that bows with your weight. Slide it up next to the turntable and drop the needle, The Sadies are a sure thing…tomorrow isn’t.
