Medicated Magic

On a 25th-anniversary set that celebrates their achievements as genre saviors and also shows how indebted jam bands are to their second-line-boogie tradition, the DDBB bring in a bevy of guests for a funky romp through 10 New Orleans classics. High point: a smoke-signal rendering of the Irma Thomas signature ”Ruler of My Heart” with jazz-pop It Girl Norah Jones and gospel pedal-steel virtuoso-turned-hippie-rock hero Robert Randolph. Bring on the crawfish. B+
