Sweet Lou is an album by jazz saxophonist Lou Donaldson, his final recorded for the Blue Note label, featuring Donaldson with a big band arranged and conducted by Horace Ott. The album was awarded 3 stars in an Allmusic review by Eugene Chadbourne who stated "the passing of time has been in some ways been kind to these efforts, blurring the original impression given of careers headed downhill. Donaldson's tone on alto saxophone, regardless of setting, sounds like Charlie Parker after he has spent the night stuffed into one of those jars of pickled eggs on the menu in particularly hardcore bars".
