Labi Siffre brings it hard with So Strong. The Legendary K.O. plus a passel of rappers signify on Katrina in a roundup of topical songs. We close by featuring the many faces of Duke Ellington’s 35-year old Sentimental Mood. We’re kind of scattered this week—it’s just a reflection of a New Orleans state of mind right along through here.  Hope there’s something here that appeals to you.
